Abstract
The article simulates the process of obtaining synthetic gas from Saryadyr coal (Pyatimetrovy seam) with steam-air and steam-oxygen blasts. Special software has been developed for the calculation, which makes it possible to determine the main chemical and technological parameters of the resulting gas for given values of the amount of gas reagents and volumetric ratios of H2/CO. The calculation was carried out in such a way that in the model gas obtained from coal, the volume ratios of H2/CO were from 1:1 to 2:1, since such ratios are usually used in organic synthesis to obtain various hydrocarbon products. To obtain the appropriate H2/CO ratios, the supply of water vapor, air, or oxygen was varied. As a result of the simulation, the influence of gas reagents on the elemental composition and gas yield, the efficiency of gasification, and the calorific value of the gas were studied. The results obtained are of particular practical interest for optimizing the process of layered coal gasification for its use as a power gas (СО, Н2, СiНj) or synthesis gas (СО, Н2).
