Abstract:
Methods for preparing integral synthesis gas conversion catalyst extrudates including an oxide of a Fischer-Tropsch (FT) metal component and a zeolite component are disclosed. The oxide of the FT metal component is precipitated from a solution into crystallites having a particle size between about 2 nm and about 30 nm. The oxide of the FT metal component is combined with a zeolite powder and a binder material, and the combination is extruded to form integral catalyst extrudates. The oxide of the FT metal component in the resulting catalyst is in the form of reduced crystallites located outside the zeolite channels. No appreciable ion exchange of FT metal occurs within the zeolite channels. The acid site density of the integral catalyst extrudate is at least about 80% of the zeolite acid site density.
Abstract:
A process is disclosed for preparing a Fischer-Tropsch catalyst precursor and a catalyst made from the precursor. The process includes contacting an 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 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 and good activity.

Abstract:
This application provides an apparatus for making a hydrocarbon with a reduced amount of an organic halide, comprising: a. a process unit comprising an effluent port, that produces and discharges the hydrocarbon comprising the organic halide; and b. a halide removal vessel with an inlet that feeds the hydrocarbon from the process unit, wherein the halide removal vessel comprises an anhydrous metal chloride and in which the hydrocarbon comprising the organic halide is contacted with the anhydrous metal chloride under anhydrous conditions to produce a contacted hydrocarbon having from 50-100 wt % of a total halide in the hydrocarbon removed.
Abstract:
Processes for decomposing organic chloride in a hydrocarbon stream may comprise contacting a hydrocarbon stream with a dechlorination element in a dechlorination zone under dechlorination conditions to provide a dechlorinated hydrocarbon product, wherein the dechlorination element may comprise a metal or metal alloy having a high surface area configuration. Such a dechlorination element may be disposed within one or more distillation columns and/or within a separate dechlorination vessel.
