This invention is for a catalyst for conversion of hydrocarbons. The catalyst contains a zeolite with one element from Group 13, Group 14, or the first series transition metals and, optionally, germanium and/or aluminum in the zeolite framework. At least one Group 10 metal, such as platinum, is deposited on the zeolite. Examples of the elements in the framework are tin, boron, iron or titanium. The catalyst is prepared by synthesizing a zeolite with one element from Group 13, Group 14, or the first series transition metals and, optionally, germanium and/or aluminum in the zeolite framework; depositing the metal; and calcining after preparation of the zeolite and before or after depositing the metal. The catalyst may be used in a process for the conversion of hydrocarbons, such as propane to aromatics, by contacting the catalyst with alkanes having 2 to 12 carbon atoms per molecule and recovering the product.
