Abstract
This invention relates to a process for alkylation of an isoparaffin with an olefin over a solid-acid catalyst, wherein at least two parallel reactors are used at the same time. When the solid acid catalyst in one or more reactors need to be regenerated, the catalyst is contacted in-situ in the reactor with a solvent to wash out the macromolecular hydrocarbons deposited on the surface of the catalyst in order to resume the high selectivity of catalyst in alkylation.
