Abstract

The process of the production of hydrocarbons from synthesis gas diluted with nitrogen according to the Fischer–Tropsch method was investigated. It was experimentally established that inert-ballasted synthesis gas facilitated an increase in selectivity for C5+ and C35+ hydrocarbons and a decrease in selectivity for C1–C4 hydrocarbons. The dilution of synthesis gas improved heat exchange conditions in the reaction zone and decreased the synthesis temperature and a temperature gradient across the catalyst bed. A loss of process efficiency upon the dilution of synthesis gas can be compensated due to an increase in the gas space velocity. The applicability of diluted synthesis gas to the production of the high-molecular-weight C35+ hydrocarbons was demonstrated.
