In present work, methods of in situ regeneration for the Co-Al2O3/SiO2 catalyst were studied. The activity and selectivity of the catalyst in the Fischer-Tropsch synthesis are shown, as well as the compositions of the products in different periods of its operation. Process parameters after regeneration regimes and before stabilization of catalyst activity were studied. The compositions of the products of the Fischer-Tropsch synthesis after the renovation of the catalyst are analyzed and compared with the initial ones.

The full-cycle pilot complex was developed of conversion of natural and associated gases into synthetic hydrocarbons by the Fischer-Tropsch method. Including all general stages of GTL technology. The experimental studies on the motor fuels synthesis from "model' of the gas composition. Having of pre-reforming step determined of the need for removal of C2+ hydrocarbons, which leads to catalyst deactivation of conversion. Shown that the obtained synthesis-gas from conversion step may be used in the hydrocarbons synthesis by the Fischer-Tropsch method. The developed composite catalyst is allowing to obtain high-quality motor fuels from one-reactor method. The Uniting steps of hydrocracking and hydroisomerization of hydrocarbons from CO and H2.
