Abstract
1432682 Two-stage isoparaffin alkylation UOP Inc 5 July 1973 [7 July 1972] 31977/73 Heading C5E An isoparaffin is alkylated in the presence of a catalyst in a first zone with a lighter olefin (e.g. propylene) at least a portion of the alkylate and unreacted isoparaffin being contacted in a second zone with a catalyst and a heavier olefin (e.g. butylene) to give a further alkylate. The isoparaffin may be isobutane, and the isoparaffin recovered from the second zone may be recycled to the first zone. Suitable catalysts for each zone are HF, H 2 SO 4 , H 3 PO 4 or a crystalline aluminosilicate. Preferably the first alkylation is carried out at 60-150 F. using 80-99 wt. per cent HF catalyst whereas the second alkylation is carried out at a lower temperature, 40-110 F., using less concentrated HF (65-95 wt. per cent).
