A method for the steam dehydrogenation of dehydrogenatable hydrocarbons, with simultaneous oxidative heating again.

摘要

A novel process is disclosed for the steam dehydrogenation of dehydrogenatable hydrocarbons in the vapor phase in conjunction with oxidative reheating of the intermediate products. The process utilizes a single catalyst to perform both the selective oxidation and steam dehydrogenation functions. The particular catalyst employed comprises a Group VIII noble metal component, a Group IA and/or a Group IIA component and may contain among other modifiers a Group IIIA or IVA metal, and a halogen component. The catalytic components are supported on an inorganic substrate such as alumina.
