Abstract
555,046. Cyclizing hydrocarbons. SHELL DEVELOPMENT CO. March 18, 1942, No. 3609. Convention date, Feb. 27, 1941. [Class 2 (iii)] Aromatic hydrocarbons are prepared by cyclization of aliphatic hydrocarbons having 6 to 12 carbon atoms, using as catalyst a compound of a metal selected from the left hand columns of Groups IV to VI of the Periodic Table, supported on a stabilizing carrier of relatively low catalytic activity, and promoted by the presence of platinum and (or) palladium. The support may be an adsorptive alumina such as alumina alpha monohydrate or "activated alumina." The catalyst, which is preferably chromium oxide and may contain zinc oxide, is impregnated with a solution of a compound of the promoter, e.g. ammonium or alkali platinum chloride or barium platinum cyanide, dried and heated. Sulphates should be absent but a small amount of a potassium compound other than sulphate may be present. Examples give the conversion of heptane to toluene.
