In one embodiment, the method for modifying the amorphous material comprises depositing an inorganic oxide or inorganic oxide precursor to the amorphous material; and treating the deposited amorphous material so as to reduce its micropore volume by at least about 5 percent, while its mean pore diameter is substantially unchanged or changed by not more than about 10 percent. Further embodiments include the amorphous material comprising silica-alumina, and the deposited inorganic oxide or inorganic oxide precursor comprising silicon.

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 is a method of forming a hybrid Fischer-Tropsch catalyst extrudate for use in synthesis gas conversion reactions. The method includes extruding a mixture of ruthenium loaded metal oxide support particles, particles of an acidic component and a binder sol to form an extrudate. The resulting extrudate contains from about 0.1 to about 15 weight percent ruthenium based on the weight of the extrudate. In a synthesis gas conversion reaction, the extrudate is contacted with a synthesis gas having a H2 to CO molar ratio of 0.5 to 3.0 at a reaction temperature of 160° C. to 300° C., a total pressure of 3 to 35 atmospheres, and an hourly space velocity of 5 to 10,000 v/v/hour, resulting in hydrocarbon products containing 1-15 weight % CH4; 1-15 weight % C2-C4; 70-95 weight % C5+; 0-5 weight % C21+ normal paraffins; and 0-10 weight % aromatic hydrocarbons.
