Abstract: A process has been developed for preparing a Fischer-Tropsch catalyst precursor and a Fischer-Tropsch catalyst made from the precursor. The process includes contacting a gamma alumina catalyst support material with a first solution containing a compound containing an element selected from the group consisting of yttrium (Y), niobium (Nb), molybdenum (Mo), tin (Sn), antimony (Sb) and mixtures thereof to obtain a modified catalyst support material. The modified catalyst support material is calcined at a temperature of at least 700° C. The calcined modified catalyst support has a pore volume of at least 0.4 cc/g. The modified catalyst support is less soluble in acid solutions than an equivalent unmodified catalyst support. The modified catalyst support is contacted with a second solution which includes a precursor compound of an active cobalt catalyst component to obtain a catalyst precursor. The catalyst precursor is reduced to activate the catalyst precursor to obtain the Fischer-Tropsch catalyst. The catalyst has enhanced hydrothermal stability as measured by losing no more than 25% of its pore volume when exposed to water vapor.

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.

The set of coolant passages conducts a coolant therethrough, and the set of reaction passages contains the hybrid catalyst therein and conducts synthesis gas and reaction products therethrough. The process is conducted at a temperature from 200 to 2800° C., a pressure from 5 to 40 atmospheres, a recycle ratio from 1 to 3, and a gaseous hourly space velocity less than 20,000 volumes of gas per volume of catalyst per hour. The effluent produced includes a hydrocarbon product containing at least 50 wt % C5+ hydrocarbons and less than 5 wt % C21+ hydrocarbons at a C5+ productivity from 0.05 to 2 gC5+/gcat/h.
