Catalytic reforming of hydrocarbons

摘要

A process is provided for converting alkanes and cycloalkanes having up to 20 carbon atoms per molecule to a product comprising hydrogen gas and dehydrogenated and/or dehydrocyclized hydrocarbons, in the presence of a catalyst composition comprising vanadium oxide and aluminum phosphate. The preferred product components are aromatics such as ethylbenzene and xylenes. In one embodiment, a substantially deactivated catalyst composition is regenerated by contacting it with a free oxygen containing gas under suitable regeneration conditions.
