  • Isoparaffin-olefin alkylation utilizing a continuous sulfuric acid phase in a tubular reaction zone
    Patent number: 3956417
    Abstract: A process for alkylating isoparaffin hydrocarbons with olefin hydrocarbons for production of high octane gasoline range alkylate wherein the alkylation reaction is performed in the presence of a sulfuric acid alkylation catalyst containing from about 0.0005 to about 0.5 weight percent of a selected micelle forming amphiphilic compound, and wherein the reaction is carried out in a non-backmixed tubular reactor.
    Type: Grant
