The gasified block of coal contained only 108.1 kg of water, so the separated water must have originated mainly from the evaporation of the moisture contained in the wet sand, and only some of it would have come from the water contained in the coal. Learning the characteristics according to Barrot (2017) of quantitative research will guide you as a researcher the standards you need to consider upon conducting your study. 0000046782 00000 n
Quantitative and qualitative research designs differ in terms of their epistemo logical, theoretical . The free space between the coal block and the reactor side walls was also filled with wet sand. Expressed ideas are open to revision. The volumes of the tar vapours were neglected in the calculations, because they constituted 0.050.15% of the combined volumes of the produced gases and water vapour. It is different from deductive reasoning, which draws aconclusionabout a particular casefrom a general law. In his analyzes and interpretations he does not include notions like freedom, will, free choice or moral responsibility.

In discussing the results obtained, it should also be taken into account that the iron contained in siderite may have had a catalytic effect in the Bouduard reaction. Note that from the first issue of 2016, this journal uses article numbers instead of page numbers. For the reasons above and because qualitative methods often are adapted and It is a method used in research that uses as a platform numerical or quantifiable data to make generalizations about a phenomenon. The high average content of the benzene in the tested tar (77.1%) indicates that it was formed as a result of thermal cracking. Data collection is also controlled by the application of instruments containing items with measurable characteristics, such as age, weight, educational level, average income, among others. Look for the words HTML. https://doi.org/10.4135/9781529624298. Rather, non-measurable data are observed and described. These investigationsnever study an isolated eventbut, to understand each event, behavior or customs, they adopt a holistic position, that is, they take into account the experience of the subject as a whole.

Its CO, The temperatures in row I of the thermocouples (fire channel) and row II of the thermocouples, as well as the temperatures at the reactor outlet and inside the wet scrubber, are shown in, The temperature measurement point of the process gas at the reactor outlet was located close to the tar-sampling connection (, The temperatures of the process gas at the inlet to the scrubber were not high, ranging from 90110 C. "Thinking of Your Research Questions: Characteristics of "Good" and "Bad" Research Questions." 18 Mar 2023. Together with the crude benzole, the yield of the coke oven tar is 4.66.1%. The water vapour gradually reacted with the coal, and, as a result, high concentrations of hydrogen and carbon monoxide were observed in the resulting gases. The review highlighted the emotional impact of diagnosis in adulthood, limited provision of formal support and inconsistencies in access and processes (Huang et al., 2020). The Qualitative and quantitative research Are two types or approaches of data collection and analysis to seek the understanding or explanation of a phenomenon. When the characteristics of quantitative or qualitative research are discussed, the four essential elements of the research process must be addressed. accrue from both quantitative and qualitative research. ORAU -U.S. Department of Energy (DOE). In one study [. sign in or create a profile so that you can create alerts, save clips, playlists and searches. At high temperatures in the reactor, in the presence of hydrogen and steam, this tar could undergo hydrocracking and steam reforming. The sand was used as an insulating material, simulating moisture in the vicinity of the gasified coal seam. ; Thorsness, C.B. Zhang, H.R. Likewise, the meaning of motherhood for the same woman will change once she becomes pregnant and has her first child. James Neill (2007). [. The proximity of the researcher to the study and the subjects allows the development of a more sensitive point of view within the field. Results of the Centralia underground coal gasification field test. Title. Characteristics of Quantitative Research. According to the second mechanism, at lower temperatures, the hydrogen that is generated can reform into the separated tar components and inhibit the repolymerisation reaction of their molecules. Wang, G.X. Korus, A.; Samson, A.; Szlk, A.; Katelbach-Woniak, A.; Sadek, S. Pyrolytic toluene conversion to benzene and coke over activated carbon in a fixed-bed reactor. It differs from quantitative research, which looks for measurable and comparable data such as percentages, quantities, and probabilities. It aims at establishing cause and effect relationship between two variables by using mathematical, computational and statistical methods. There has been much debate among scholars in recent decades about the merits and shortcomings of both research strategies, especially in the social sciences. 0000003800 00000 n

The following are the strategies in qualitative research: 1. Nitrogen is used for inerting the installation and for cooling the reactor after the gasification process is complete. They tend to be deep studies of small groups of people with whom the hypothesis is established, to describe in depth a phenomenon, social reality, culture, behavior or experience. Qualitative research does not usually allow statistical analysis. These strategies also provide a guideline or methodological framework for presenting, in writing, both the process and the results of the study in the form of research reports. The presence of the researcher ends up having a significant impact on the subjects. If the observations are not repeatable, both results and conclusions are considered to be unreliable. When studying a social group or a society far from his own, the qualitative researcherdoes not judge the attitudes and thoughts of that group from his own point of viewbut tries to understand it within the framework ofvalues,norms, practices and beliefs of the group studied. Sign up for a free trial and experience all Sage Research Methods has to offer. The dimensions of the gasified coal block were 3.8 0.7 0.7 m (width, depth, and height). Qualitative research takes time and requires more work than other types of research. This test gives weight to the study. The ex situ coal gasification studies presented in the article were aimed at identifying this problem to a significant extent. Quantitative vs. Qualitative - Texas A&M University-Commerce Hill, R.W. Facilitates a horizontal relationship with the investigated groups. An estimation of the efficiency of the tar production from the gasified coal was made, taking into account the total amount of the gasified coal, which was 532.8 kg.

Mixed research - research that involves the mixing of quantitative and qualitative methods or paradigm . Its heavier components condense in the higher temperature zone, while its lighter components condense in places closer to the surface, where the temperature is lower. Taking into account a 30% error in underestimating the amount of tar that was obtained, it was calculated that the yield of the tar in this process was approximately 1.8% of the mass of the gasified coal. Wiley has partnerships with many of the worlds leading societies and publishes over 1,500 peer-reviewed journals and 1,500+ new books annually in print and online, as well as databases, major reference works and laboratory protocols in STMS subjects. Retrieved from orau.gov. What is Qualitative Research? The operationalization is essential to identify the measurable elements that define the variables that interact, establishing the empirical referents or terms within it. As ethane is released during the cracking of the tar, the increase in ethane during these time intervals indicates the occurrence of cracking processes in the tar produced. Pirard, J.P.; Brasseur, A.; Come, A.; Mostade, M.; Pirlot, P. Results of tracer test during the El Tremedal underground coal gasification at great depth. ; Li, S.; Kelly, K.E. What Is Qualitative Research? Often the results are fairly banal or trivial, with no significant consequence given the restrictive and controlled nature of the variables. The yield of the crude benzol is typically 1.1% of the weight of the coked coal. We use cookies to provide our online service. Political Science and International Relations. The description. The analysis of the siderite was carried out at the Silesian Interdisciplinary Education and Research Centre in Chorzw. When comparing the tar yield from the UCG process with the tar yield from a classic coal coking process, it should be taken into account that the coke oven tar yield is approximately 3.55% of the weight of the coked coal. papers requested by the individual editor responsible for the issue and a member Quantitative research is a form of research that relies on the methods of natural sciences, which produces numerical data and hard facts. For this reason, the nature of quantitative research is descriptive and necessarily both the subject and its variables and elements of the problem must be able to be defined, measured or translated into numbers. 0000004334 00000 n
Starting from the 46th hour of the process, an increase in the amount of ethane produced is also visible. You are accessing a machine-readable page. It is assumed that the possible inaccuracies of the results presented in this work result from the imprecise determination of hydrocarbon concentrations in tar samples taken into sorption tubes. To examine, compare and assess education policies, trends, reforms and This visualization demonstrates how methods are related and connects users to relevant content. For this purpose, the ratio (in percentage) was calculated from the area of the peaks corresponding to the analysed compounds, divided by the sum of the areas of all the peaks obtained in the spectrum. This reaction is favoured [, Numerical simulation, in addition to the experiments, can also be effectively applied to the study of tar formation and conversion in UCG. "An Experimental Study on the Quantitative and Qualitative Characteristics of Tar Formed during Ex Situ Coal Gasification" Energies 16, no. ; Campbell, S.L. Present Data in Tables, Graphs, or Figures 5. Jones & Bartlett Learning. Qualitative research strategies. Qualitative research provides flesh and blood to social analyzes. The moisture content in the sand, determined in accordance with the PN-G-04511:1980 standard, was 11.0%. The results of the ex situ coal gasification presented in the article show that, during this process, tar was released with different intensities, and its efficiency and composition depended on the gasification parameters. %%EOF
On the one hand are those who see both approaches as separate entities that are based on different and interchangeable visions of the world, and on the other hand those who are more than comfortable with combining the methods by seeing them as complementary. It seems that, under the conditions prevailing in the reactor (a high temperature at the beginning and a lower temperature at the end, and the presence of hydrogen and steam), apart from cracking, some reforming processes (isomerisation, cyclization, and aromatisation) could have taken place. T. his chapter focuses on research designs commonly used when conducting . Tar reforming using the supported potassium carbonate. There was an increase in the proportions of the BTEX compounds and phenol compounds, and a decrease in the proportion of the PAH compounds. As the reaction progressed, the water that was contained in the wet sand started to react with the gasified coal, which significantly affected the composition and amount of the obtained process gas and the produced tar. He not only covers Technical articles but also has skills in the fields of SEO, graphics, web development and coding. Effects of Moisture content in Coal on Pyrolysis Behavior in indirectly Heated Fixed-Bed Reactor with Internals. This was most likely the result of the gasification zone moving closer to the wet sand. Compared to a quantitative research, the advantages of a qualitative research are: The results lose objectivity because they depend on the interpretation of the researcher. The various tech-niques used to ensure rigour in qualitative research are described The obtained results of the technical and elemental analysis of the coal are shown in, The analysed bituminous coal was characterised by a low moisture content (as received) of 4.7%, a relatively high ash content of 16.30%, and a volatile matter content of 30.10%. Klebingat, S.; Kempka, T.; Schulten, M.; Azzam, R.; Manuel Fernndez-Steeger, T.M. Producing Hydrocarbons by the Underground Gasification of Coal. Whether it is the best of two worlds in the universe of scholarly works, or lines of research that when integrated into the same study will contaminate each other, the two approaches meet the main objectives in an investigation. Some of the characteristics were, identified through word play, graphs, numbers, and mathematical techniques. Qualitative is usually more subjective, although like quantitative research, it also uses a systematic approach. Answer a handful of multiple-choice questions to see which statistical method is best for your data. able to comprehend what is being investigated or studied. In addition tostudying processes in society, the researcher takes into account the way his own research progresses.

The error that was calculated on this basis was approximately (minus) 30% of the total tar mass. Depending on the phenomena the researcher encounters, he can hypothesize and correct concepts as he goes along. The results that were obtained were recalculated into the concentrations of the individual components of the tar and its mass stream in the process gas. Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for See further details. Over the three-day gasification test of a large coal block with oxygen in atmospheric pressure conditions, the yield and composition of the tar collected was investigated. 75 0 obj<>stream
This is because, during the process, the gasification zone was expanding, which meant that subsequent amounts of coal were gasified, producing new amounts of tar. Qualitative research acknowledges the subjectivity of the researcher and the participants, and recognizes that multiple perspectives and interpretations are possible. Qualitative investigations can be complemented with other quantitative ones. One of the reasons why qualitative research does not seek universal generalizations is because itdoes not focus on fixed situations or invariant statesof a society, but rather studies processes. The time for data collection, analysis and interpretation of data is extensive. Quantitative methodology is the dominant research framework in the social sciences. Russian Patent 64,509, 30 April 1945. Theresearchercan interact directly through theinterviewor through participation in activities in thecommunityhe studies. Quantitative Methods: Meaning and Characteristics. ; Jung, D.; Miyawaki, J.; Yoon, S.H. By using both quantitative and qualitative data, researchers have a more holistic, well-rounded understanding of a particular topic or phenomenon. New knowledge from the results emerges through an inductive process. It is endothermic and reversible. Thinking of your research questions: characteristics of "good" and "bad" research questions [Video]. The consumption of this amount of energy must have lowered the temperature in the reactor, as shown in the temperature diagrams. The results that were obtained are presented in, From the graphs of the mass flows of the BTEX, PAHs, and phenols, as shown in, The residence time of the tar vapours in the reactor can be calculated based on the temperatures in the reactor, the geometry of the reactor, and the amount of gases and water released in the process.
