Abstract
Abstract Hydrocarbons are dehydrocyclized to aromatics over a new catalyst comprising a carrier such for example as alumina, platinum, at least one metal selected from iridium, tungsten and ruthenium, cobalt, at least one metal selected from the group consisting of copper, manganese, silver and gold, and at least one halogen such for example as chlorine.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
108 words
In a process for the production of aromatic hydrocarbon by cyclization, dehydrogenation or dehydrocyclization of an appropriate starting compound over a catalyst, the improvement which comprises employing as said catalyst, a catalyst consisting essentially of (a) a carrier and, expressed in proportion by weight with respect to the carrier, (b) 0.005 to 2% of platinum, (c) 0.005 to 1% of a metal selected from the group consisting of iridium, rhodium and ruthenium, (d) 0.05 to 0.8% of cobalt, (e) 0.005 to 1% of at least one metal selected from the group consisting of copper, manganese, silver and gold, and (f) 0.1 to 10% of at least one halogen.
