Abstract
1,128,262. Benzene. ATLANTIC RICHFIELD CO. 24 March, 1966 [13 Sept., 1965], No. 12937/66. Heading C5E. Benzene is produced by non-catalytic dealkylation of alkylbenzenes at 1100-1500 F., 500-800 p.s.i.g., and in contact with a hydrogen rich gas, the reaction being quenched with hydrogen to maintain a temperature difference of not more than 200 F. between maximum and minimum temperatures within the reaction zone, the reaction effluent being cooled to stop the reaction, and the benzene product being separated from hydrogen in a flash chamber, from light hydrocarbon gases in a first fractionating zone and from unreacted alkyl benzenes in a second fractionating zone, a sidestream of benzene together with hydrocarbons forming azeotropic boiling mixtures with benzene being removed from the first fractionating zone and returned to the reaction zone.
