Abstract
An improved HF alkylation process for producing alkylated isoparaffins wherein capital cost, operating costs and energy consumption are reduced by elimination of the necessity of the commonly-included catalyst regeneration facilities. Hydrocarbonaceous polymers which form collateral to alkylation reactions occurring in a reaction zone, and which contaminate the acid catalyst therein, are routed to pass through reboiling means of two fractionators whereby HF and some combined fluorides in the polymers are removed and the polymers exit the process with an alkylate product. Some decomposition of the combined fluorides prevents fluorine contamination of the alkylate product.
