Abstract
This invention is for a catalyst for conversion of alkanes having two to six carbon atoms per molecule to aromatics. The catalyst is a MFI zeolite with a crystallite size of less than 15 microns with, in addition to silicon and aluminum, germanium as a framework element. Platinum is deposited on the zeolite. The zeolite may contain other optional tetravalent and trivalent elements in the zeolite framework. The catalyst is synthesized by preparing a zeolite containing aluminum, silicon, germanium and, optionally, other elements in the framework, calcining the zeolite and depositing platinum on the zeolite. The catalyst may be used for aromatization of alkanes, such as propane, to aromatics, such as benzene, toluene and xylenes.
