CATALYST OF FISCHER-TROPSCH SYNTHESIS, METHOD OF ITS MANUFACTURING AND METHOD OF OBTAINING HYDROCARBONS Russian patent published in 2015 - IPC B01J23/75 B01J35/10 B01J37/10 B01J37/18 C10G2/00 

Abstract RU 2552517 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst of the Fischer-Tropsch synthesis, containing from 10 to 30 wt % counted per atomic metal, metal cobalt and/or cobalt oxide, with respect to the weight of the catalyst, supported on a carrier, containing silica, in which the carrier has an average pore diameter from 8 to 25 nm, and metal cobalt and/or cobalt oxide has the average diameter of crystallites not smaller than the average diameter of the carrier pores and smaller than 35 nm, with the catalyst containing from 0.5 to 10 wt % of zirconium in the form of zirconium oxide, counted per the catalyst weight. The invention also relates to a method of the catalyst manufacturing, as well as to methods of obtaining hydrocarbons.

EFFECT: obtaining the catalyst, possessing improved catalytic activity due to the regulation of active metal distribution between the space inside the pores and the space outside the pores of the porous-inorganic carrier.
