Abstract
Disclosed are hybrid Fischer-Tropsch catalysts containing cobalt deposited on hybrid supports. The hybrid supports contain an acidic zeolite component and a silica-containing material. It has been found that the use of the hybrid Fischer-Tropsch catalysts in synthesis gas conversion reactions results in high C5+ productivity, high CO conversion rates and low olefin formation.

A hybrid Fischer-Tropsch catalyst comprising:
- a. a hybrid support having a pore volume of from 0.4 cc/g to 1.4 cc/g and a BET surface area of from 100 to 450 m2/g, the hybrid support comprising:
- i. at least one zeolite comprising at least 20 wt % of the hybrid support;
- ii. a binder material comprising at least 10 wt % of the hybrid support;
- and
- iii. a material selected from the group consisting of a silica-containing material, an alumina-containing material and a combination thereof comprising from 20-70 wt % of the hybrid support;
- and
- b. a Fischer-Tropsch component comprising 15 to 45 wt % cobalt deposited on the hybrid support.
