Catalyst for the hydroisomerization and hydrocracking of waxes to produce liquid hydrocarbon fuels and process for preparing the catalyst

摘要

A fluorided platinum-on-alumina catalyst for wax isomerization wherein the platinum is substantially uniformly distributed throughout the catalyst in the form of relatively small crystallites, of the total fluoride present in the catalyst very little is located on the outer surface of the catalyst and a significant concentration of the fluoride within the catalyst is present as aluminum fluoride hydroxide hydrate. The catalyst is prepared by contacting a platinum-on-alumina with a solution having a relatively high concentration of fluoride and drying the fluorided platinum-on-alumina catalyst at temperatures not in excess of 650 F.
