Abstract
A process for liquid phase alkylation of a hydrocarbon substrate with an olefinic alkylating agent comprising the steps of passing a process stream of the hydrocarbon substrate and alkylating agent at alkylating conditions through a fixed bed alkylation reactor of particulate polar contact material in the presence of a fluorinated sulfonic acid catalyst.

A process for liquid phase alkylation of a hydrocarbon substrate with an olefinic alkylating agent in the presence of a fluorinated sulfonic acid catalyst in a fixed bed alkylation reactor of particulate polar contact material comprising the steps of:
- establishing on the polar contact material a reaction zone with the fluorinated sulfonic acid absorbed on a confined area of the contact material;
- passing a process stream of the hydrocarbon substrate and alkylating agent at alkylating conditions in one flow direction through the reactor;
- withdrawing a product stream of alkylated products from the reactor;
- and
- periodically reversing the flow direction of the process stream as the fluorinated sulfonic acid has passed substantially through the reactor.
