Improved alkylation catalysts, alkylation methods, and methods of making alkylation catalysts are described. The alkylation method comprises reaction over a solid acid, zeolite-based catalyst and can be conducted for relatively long periods at steady state conditions. The alkylation catalyst comprises a crystalline zeolite structure, a Si/Al molar ratio of 20 or less, less than 0.5 weight percent alkali metals, and further having a characteristic catalyst life property. Some catalysts may contain rare earth elements in the range of 10 to 35 wt %. One method of making a catalyst includes a calcination step following exchange of the rare earth element(s) conducted at a temperature of at least 575 C. to stabilize the resulting structure followed by an deammoniation treatment. An improved method of deammoniation uses low temperature oxidation.

Disclosed herein is a process for preparing a hydrocracking catalyst, comprising (i) combining a zeolite, a binder, water and a hydrogenating metal compound which is a complex or a salt of a hydrogenating metal to obtain a mixture, wherein the zeolite has not been treated with a phosphorus-containing compound and the zeolite has a silica to alumina molar ratio of 5-200; (ii) forming the mixture into a shaped body; and (iii) calcining the shaped body to form the catalyst.
