Abstract
The invention discloses a synthetic gas conversion catalyst. According to the synthetic gas conversion catalyst, modified silica gel is taken as a carrier; cobalt is taken as an active component, and accounts for 5 to 35wt% of the synthetic gas conversion catalyst; and the modified silica gel is modified with a zinc-containing aqueous solution with a pH value of 3 to 4.5 via excessive immersion treatment. The invention also discloses a preparation method of the synthetic gas conversion catalyst. The preparation method comprises following steps: silica gel is taken as the carrier, and is subjected to surface modification, wherein excessive immersion treatment with the zinc-containing aqueous solution with a pH value of 3 to 4.5 is used for surface modification of the silica gel carrier; and loading of the active component Co is carried out via immersion method. The invention also discloses applications of the synthetic gas conversion catalyst in Fischer-Tropsch synthetic reaction. The preparation method is simple; and the synthetic gas conversion catalyst is high in activity and stability.
