| 摘要 |
In the HF alkylation of isoparaffins with olefins an improved process is provided comprising charging isoparaffin, olefin(s), and HF catalyst to the upstream end of a vertically extended reaction zone, introducing the same or different olefin(s) and, optionally, isoparaffin, downstream along with a recycled alkane stream separated from the alkylation effluent under alkylation conditions to produce high octane alkylate. In a preferred embodiment, the recycle alkane stream is propane and/or normal butane.
