Abstract
Abstract A process and catalyst for the conversion of hydrocarbons is disclosed. The catalyst is supported solid perfluorinated polymer containing pendent sulfonic acid groups. The processes include alkylation of isoparaffins, isomerization of normal alkanes, disproportionation of toluene, and the alkylation of benzene.
