CATALYST AND METHOD FOR PREPARING HYDROCARBONS Russian patent published in 2005 - IPC

Abstract RU 2259988 C2

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for preparing mainly C₅₊-hydrocarbons. Method involves contacting carbon monoxide with hydrogen at temperature 180-270°C and under increased pressure in the presence of catalytic composition comprising as measure for the total mass of catalytic composition from 5 to 30 wt.-% of cobalt, from 0.01 to 5 wt.-% of manganese and at least from 0.01 to 0.9 wt.-% of rhenium and/or ruthenium on a carried made of titanium dioxide. Invention provides reducing amount of carbon dioxide evolved in the process of hydrocarbons synthesis by Fisher-Tropsh to the level 2% vol./vol., not above, but preferably to 1% vol./vol., not above, and without reducing C₅₊-selectivity.

EFFECT: improved preparing method.
