ABSTRACT:
An alkylation process wherein isoparaffin hydrocarbons are alkylated with olefin hydrocarbons in the presence of an alkylation catalyst comprising H.sub.2 SO.sub.4 to yield alkylated hydrocarbons suitable for use in motor fuels. Such process includes an isoparaffin pretreatment step wherein isoparaffin charge is contacted with spent alkylation catalyst to remove contaminants from the isoparaffin which are reactive with sulfuric acid under alkylation conditions.
