METHOD OF PREPARING CATALYST PRECURSOR, CATALYST PREPARATION METHOD, AND A PROCESS FOR PRODUCTION OF HYDROCARBONS USING THUS PREPARED CATALYST Russian patent published in 2006 - IPC B01J37/02 B01J37/00 B01J23/75 B01J21/06 C07C1/04 C10G2/00 

FIELD: organic synthesis catalysts.

SUBSTANCE: invention relates to methods for preparing catalyst precursors and group VIII metal-based catalysts on carrier, and to a process of producing hydrocarbons from synthesis gas using catalyst of invention. Preparation of precursor of group VIII metal-based catalyst comprises: (i) imposing mechanical energy to mixture containing refractory oxide, combining catalyst precursor with water to form paste comprising at least 60 wt % of solids, wherein ratio of size of particles present in system in the end of stage (i) to that in the beginning of stage (i) ranges from 0.02 to 0.5; (ii) mixing above prepared paste with water to form suspension containing no more than 55% solids; (iii) formation and drying of suspension from stage (ii); and (iv) calcination. Described are also method of preparing group VIII metal-based catalyst using catalyst precursor involving reduction reaction and process for production of hydrocarbons by bringing carbon monoxide into contact with hydrogen are elevated temperature and pressure in presence of above-prepared catalyst.

EFFECT: increased catalytic activity and selectivity.
