Feature papers represent the most advanced research with significant potential for high impact in the field. 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. When the characteristics of quantitative or qualitative research are discussed, the four essential elements of the research process must be addressed. Kaiser, M.; Wanzl, W. Characterization And Comparison Of Liquid Products From Coal Pyrolysis In Laboratory And Process Development Units. In the produced tar, the concentrations of the BTEX and phenol compounds decreased, while the concentration of the PAH compounds increased, and then decreased again between 1534 h. As a result, the molecular weight of the tar increased, and the H/C ratio was lowered. A flame ionisation detector (FID) was used to analyse the BTEX compounds and phenols, while a chromatograph coupled with an Agilent 5975C mass spectrometer in Selected Ion Mode (SIM) were used to detect the PAH compounds. Due to the high temperature, a large amount of water vapour began to escape from the sand and reacted with the incandescent coal. ; Jung, D.; Miyawaki, J.; Yoon, S.H. Quantitative designs can be experimental, quasi-experimental, descriptive, or correlational. The curves of the temperature changes that are presented in. This visualization demonstrates how methods are related and connects users to relevant content. Qualitative research involves a detailed and in-depth analysis of data, with a focus on identifying themes, patterns, and relationships that emerge from the data. Common quantitative methods include experiments, observations recorded as numbers, and surveys with closed-ended questions. The steam generated, in addition to producing process gas components, stimulated the release of tar from the gasified coal. 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. As a result, data collection and analysis sections might be combined.

Rahimi examined the effects of revision in focused and comprehensive written corrective feedback.

Oak Ridge Institute for Science and Education. It is open to the use of images, conversations, narratives, texts and observations in context. 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. Qualitative versus Quantitative Research: Key Points in a Classic Debate. 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. The researcher tries to understand his object of study within his own framework. %PDF-1.4 % The error that was calculated on this basis was approximately (minus) 30% of the total tar mass. The moisture content in the surroundings of the gasified block of coal had a significant impact on the gasification process, because the water reacted with the glowing coal and produced large amounts of process gas that was rich in hydrogen and carbon monoxide. 3.0. Based on library sources, the paper is prepared for the Bachelor and Master level research students plus interested ones. Qualitative Research: Definition and Principles. Available at: > 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. The presented data show that, during the gasification test, tar products were constantly present in the process gases.
