Abstract: A heavy metal poisoned, spent FCC catalyst is treated by chemically impregnating the poisoned catalyst with a new catalytic metal or metal salt to provide an attrition resistant catalyst or sorbent for a different catalytic or absorption processes, such as catalysts for Fischer-Tropsh Synthesis, and sorbents for removal of sulfur gasses from fuel gases and flue-gases. The heavy metal contaminated FCC catalyst is directly used as a support for preparing catalysts having new catalytic properties and sorbents having new sorbent properties, without removing or "passivating" the heavy metals on the spent FCC catalyst as an intermediate step.

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 is contacted with a second solution which includes a precursor compound of an active cobalt catalyst component and an organic compound, preferably glutaric acid, 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. The catalyst has Co3O4 crystallites having an average size of no greater than 20 nm. As a result, the catalyst has good activity.

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: Processes and systems are provided for converting synthesis gas containing a mixture of H2 and CO to liquid hydrocarbon products having a cloud point less than about 15° C. The systems utilize at least one Fischer-Tropsch reactor containing hybrid Fischer-Tropsch catalyst with cooling and separation of reactor effluent following each reactor. The low cloud point indicates that the amount of wax in the hydrocarbon products is minimized relative to conventional Fischer-Tropsch conversion. Accordingly, more economical systems can be built and operated because equipment associated with wax removal or wax treatment can be reduced or eliminated.

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.
