Abstract
A method of regenerating an acidic catalyst is described. A silane compound is contacted with an acidic catalyst that contains conjunct polymer, which releases the conjunct polymer from the acidic catalyst. The acidic catalyst can then be re-activated with acid. The conjunct polymer can be separated from the silane compound, and the silane compound can be recycled.
