Production of Hydrocarbon Fuel from Synthesis Gas Obtained by the Gasification of Oil Shales

Аннотация

The Fischer-Tropsch synthesis was carried out over cobalt catalysts using gas from oil shale as a model. A broad hydrocarbon fraction can be obtained over cobalt catalysts using model mixtures (CO + CO₂+ H₂+ N₂) from Leningrad and Kashpir oil shale products. A study was carried out on the effect of the synthesis gas composition, support and promoter type, temperature, pressure, and volumetric stock feed rate on catalyst efficiency, carbon monoxide conversion, as well as the selectivity and yield of the liquid products. Liquid hydrocarbon selectivity up to 88.7% was achieved with low methane selectivity (3.3%). The hydrocarbons obtained show chain growth probability up to 0.87.
