    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: Disclosed are a process and a system for synthesis gas conversion. The process includes contacting a synthesis gas feed of hydrogen and carbon monoxide having a H2/CO ratio from 0.5 to 3.0 with a hybrid catalyst of particles having a particle size from 50 to 500 μm and having at least one zeolite and a Fischer-Tropsch component wherein the ratio of zeolite to Fischer-Tropsch component is from 0.1:1 to 30:1 and the hybrid catalyst includes from 0.5 to 40 wt % Fischer-Tropsch component. The process is conducted in a compact heat exchange reactor having a set of reaction passages disposed between a synthesis gas feed header and a products header and a set of coolant passages disposed between a coolant inlet header and a coolant outlet header. 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.

    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 vanadium compound, 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 0.35 cc/g. The modified catalyst support is less soluble in acid solutions than an equivalent unmodified catalyst support. The modified catalyst support loses no more than 15% of its pore volume when exposed to water vapor. 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 22% 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 vanadium compound and a phosphorus compound, 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 loses no more than 6% of its pore volume when exposed to water vapor. 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 10% of its pore volume when exposed to water vapor.
