Abstract
There are provided a catalyst, a method for making this catalyst, and a process for using this catalyst in the alkylation of an isoparaffin with an olefin to provide an alkylate. The catalyst may be made from an as-synthesized material which, upon calcination, is capable of generating zeolites designated MCM-22. The as-synthesized material is then combined with a binder material, such as alumina, by an extrusion process. The uncalcined bound material may then be ammonium exchanged, followed by a calcination treatment. The as-synthesized material may also be swollen with a suitable swelling agent, such as a cetyltrimethylammonium compound, prior to the binding process.
