PCT No. PCT/EP89/01517 Sec. 371 Date Aug. 9, 1991 Sec. 102(e) Date Aug. 9, 1991 PCT Filed Dec. 12, 1989 PCT Pub. No. WO90/06907 PCT Pub. Date Jun. 28, 1990.Process and catalyst for dehydrogenation or dehydrocyclization of hydrocarbons. The catalyst consists of an aluminum oxide/chromium oxide support with promotors consisting of compounds of alkali metals and/or alkaline earth metals and compounds of metals from the third and/or fourth subgroups of the periodic table. Coke formation and side reactions can be substantially suppressed by the use of these catalysts under special operating conditions and special reactors.
