Abstract
Method and means are described for the conversion of lower molecular weight paraffins and olefins to high octane gasoline rich in alkylated aromatics. In a two stage process catalyzed by metallosilicate, crystalline, shape selective zeolite comprising a high temperature first stage and a lower temperature second stage, the ratio of olefins to paraffins in the second stage is maintained at a level sufficient to maintain essentially isothermal reaction conditions. Novel means for effecting the conversion include transport riser reactor and turbulent bed reactor combination.
