Реферат: The effect of the gas recirculation mode on the selectivity and deactivation rate of the Co-Al2O3/SiO2 catalyst of the Fischer‒Tropsch synthesis at high pressure (6 MPa) has been studied. The use of recirculation with a gas recycle ratio of up to 2.2 promotes the formation of C19+ hydrocarbons due to the readsorption of gaseous olefins and their involvement in chain propagation. The increased selectivity for C19+ paraffin leads to accelerated deactivation of the catalyst. An increase in the gas recycle ratio to 8 leads to increased selectivity for C5+ olefins and a lower yield of C19+ waxes due to the removal of C5+ olefin vapors from the reaction zone. The latter is associated with a decreased contribution of the readsorption of higher C5+ olefins to the elongation of the carbon chain. At high gas recycle ratios, CoO was reduced to the metal, which partially compensates for catalyst deactivation as a result of the blocking of the active sites of chain propagation by C19+ waxes.
