Description

technical field [0001] The present invention relates to a catalyst composition used in the production of hydrocarbons from a mixed gas mainly composed of hydrogen and carbon monoxide (hereinafter referred to as "synthesis gas") by the Fischer-Tropsch (FT) reaction, and the production of hydrocarbons from the above-mentioned synthesis gas by the FT reaction. hydrocarbon method. More specifically, it relates to a method for producing hydrocarbons comprising a catalyst composition containing copper sulfate and an FT active metal supported on a composite carrier, and using the aforementioned FT synthesis catalyst. Background technique [0002] As methods for synthesizing hydrocarbons from synthesis gas, Fischer-Tropsch reaction, methanol synthesis reaction, and the like are known. The synthesis technology in indirect coal liquefaction was first discovered by German scientists Frans Fischer and HansTropsch in 1923 and named after their first letter, F-T, referred to as F-T synth...
