The effect of the preparation method of bifunctional cobalt catalysts with HZSM-5 zeolite and a boehmite binder on the catalytic performance in the Fischer–Tropsch synthesis was studied. The synthesized catalysts were characterized by means of BET, XRD, EDX, SEM, TEM, H2 TPD and NH3 TPD methods and tested in the synthesis of hydrocarbons at a pressure of 2.0 MPa, temperature 240 °C, and gas hourly space velocity 1000 h–1. It was shown that the method of catalyst preparation can be used for controlling the hydrocarbon and fractional composition ofproducts of the Fischer – Tropsch synthesis. A promising composite catalytic system for the single-step synthesis of low-freezing diesel fuel was proposed.

Fischer Tropsch Synthesis

The effect of syngas dilution with nitrogen on the activity, selectivity and capacity of the Fischer–Tropsch reactor with a fixed granulated catalyst bed was studied during the synthesis at the integrated pilot plant for conversion of natural gas to syncrude. Experimental data were obtained at different nitrogen content in syngas: up to 2, 50 and 70 %. The analysis of experimental data shows that the dilution of syngas increases the selectivity to C5+ and decreases the selectivity to methane. The decrease in the reactor capacity observed upon dilution of syngas can be compensated by increasing the syngas flow rate. A decrease in the pressure of the Fischer–Tropsch synthesis from 2 to 1.5 and 1.0 MPa was shown to exert a detrimental effect on the catalytic performance of the process carried out with a twofold dilution of syngas at its hourly space velocity of 4000 h–1.
