<p>Solid acid catalysts for use in alkylation processes are described. The solid acid catalysts include a multimetallic (e.g. bimetallic, trimetallic or tetrametallic) component that performs a hydrogenating function for the reactivation (or regeneration) of the catalyst in the presence of hydrogen. The multimetalic catalyst includes a noble metal such as platinum or palladium. The invention also relates to alkylation processes using the multimetallic solid acid catalysts having a multimetallic component for hydrogenation.</p>
