    Abstract: Disclosed are hybrid Fischer-Tropsch catalysts containing cobalt and ZSM-48 zeolite. The hybrid Fischer-Tropsch catalysts can contain cobalt deposited on ZSM-48 extrudate supports. Alternatively, the Fischer-Tropsch catalysts can contain cobalt deposited on supports mixed with ZSM-48 particles. It has surprisingly been found that the use of hybrid Fischer-Tropsch catalysts containing ZSM-48 zeolite in synthesis gas conversion reactions results in improved C5+ productivity and catalyst activity, as well as a desirable product distribution including low formation of methane and C21+.

    Abstract: A catalyst and method for producing hydrocarbons using a catalyst support having an improved hydrothermal stability, such as under Fischer-Tropsch synthesis conditions. The stabilized support is made by a method comprising treating a boehmite material in contact with at least one structural stabilizer. Contacting the boehmite with at least one structural stabilizer can include forming a mixture comprising the boehmite material and at the least one structural stabilizer. The mixture can be a sol or a slurry. The treating preferably includes drying or spray drying the mixture, and calcining in an oxidizing atmosphere to obtain the stabilized support. Preferred structural stabilizers can include an element, such as cobalt, magnesium, zirconium, boron, aluminum, barium, silicon, lanthanum, oxides thereof, or combinations thereof; or can include precipitated oxides, such as a co-precipitated silica-alumina.

    Abstract: The invention generally relates to methods for modifying a porous amorphous material comprising micropores to reduce its micropore volume and to form a support for a hydroprocessing catalyst, to methods of making said catalyst, as well as to methods for hydrocracking employing said hydroprocessing catalyst characterized by a lower selectivity towards undesirable gaseous hydrocarbon products. 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: 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 zinc and optionally containing P, Ti, V, Co, Ga, Ge, Mo, W and/or Pr to obtain a modified catalyst support material. The modified catalyst support material is calcined at a temperature of at least 500° 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 20% of its pore volume when exposed to water vapor.
