Abstract
Underground coal gasification gases contain CO and H2; therefore, they can be used as raw materials in the synthesis of higher hydrocarbons. The possibility of obtaining a wide-cut hydrocarbon fraction on a cobalt catalyst was demonstrated with the use of CO-H2-N2 and CO-CO2-H2-N2 model mixtures as an example. In this case, the selectivity for C5+ hydrocarbons was to 96% at a low yield of methane. The resulting hydrocarbons were characterized by a chain-growth probability to 0.89.
