STUDY OF THE CHEMICAL COMPOSITION OF COKE OVEN GAS FROM UZGEN COAL

Abstract

One of the possible ways to use Kyrgyz coal, which is the subject of research in this work, is thermal processing for the production of coke, chemical coking products, gas and other products. To study KR coal, the process of high-temperature pyrolysis was used. The object of the study was coal from the Changet coal mine in the Uzgen region. The purpose of the research is to create a coke-chemical production; the composition of gaseous substances of high-quality coke gas from the Uzgen coal basin, the largest and most promising coal deposit basin in Kyrgyzstan, has been studied using the electrochemical method using gas analyzers. As a result of research, all main groups of chemical reactions proceed in parallel; as a result of thermochemical changes, liquid gases and solid products are formed. Based on the results of the research obtained, it is necessary to resolve two main issues: assessing the quality of raw materials - ensuring the efficiency of the process of obtaining materials and target products. The originality and scientific value of the results obtained during the research, the diversity of the structure and properties of coal expands the task of researchers to find ways to optimally use their energy potential, which, in turn, determines the range of scientific research aimed at the processes of processing coal for fuel and non-fuel purposes. The practical significance is that at 500-550°C the plastic mass of coal decomposes with the formation of primary products of gas and tar, consisting of paraffin and naphthene.
