Catalytic cracking and dehydrocyclizing of alkanes using alkaline earth oxides promoted with manganese oxide and/or rhenium oxide

摘要

Alkanes are catalytically converted employing a catalyst comprising at least one alkaline earth oxide together with a promoting amount of manganese oxide and/or rhenium oxide. When the catalyst is treated with an oxygen-containing gas, such as air, prior to contacting the alkanes conversion by cracking is favored. When the catalyst is treated with hydrogen prior to contacting the alkanes dehydrocyclization is favored. A composition of matter is disclosed suitable for use as a catalyst for converting alkanes.
