Catalyst for conversion of hydrocarbons, process of making and process of using thereof—bimetallic deposition

摘要

This invention is for a catalyst for conversion of hydrocarbons. The catalyst is a non-acidic germanium zeolite, such as Ge-ZSM-5, on which at least two metals, platinum and at least one other metal selected from Group 7, Group 8, Group 9, Group 10 and tin, are deposited on the germanium zeolite. Examples of the other metal are iridium, rhenium, palladium, ruthenium, rhodium, iron, cobalt and tin. The catalyst is prepared by synthesizing a germanium zeolite; depositing platinum and at least one other metal on the germanium zeolite; and calcining after preparation of the zeolite, before depositing the metals or after depositing the metals. The catalyst may be used in a process for the conversion of hydrocarbons, such as propane to aromatics, by contacting the catalyst with a hydrocarbon stream containing alkanes, olefins and mixtures thereof having 2 to 12 carbon atoms per molecule and recovering the product.
