摘要: The invention concerns a process in which monoolefins are used to alkylate isoparaffins in the presence of an HF catalyst. An olefinic feed (14) containing dienes is selectively hydrogenated in zone (2) to reduce its diene content, and used for the HF alkylation of isoparaffin feed (26) in alkylation reactor (8). The reactor effluent (40) is passed to isostripper (32) for separation of product alkylate (54). The proportion of C₃ hydrocarbons in the alkylation reactor feed (30) is minimized by passing the selective hydrogenation product (24), the isoparaffin feed (26) and a recycle stream (28) into an alkylation feed stripper (23), providing an overhead C₃ stream (78, 86) and a bottoms (30) used as alkylation reactor feed. The recycle stream (28) is obtained from the overhead (58) of isostripper (32) after passing through HF stripper (12).
