ABSTRACT:
High quality alkylate is produced by HF alkylation of isoparaffins with olefin in a riser-reactor-type cyclic alkylation process by charging the total isoparaffin feed and HF acid catalyst to the inlet of the riser-reactor and introducing separate spaced streams of olefin in decreasing quantities along the length of the riser-reactor under conditions such as to effect high isoparaffin to olefin molar ratios along the flow path thereby avoiding the detrimental effects of unavoidable increases in reaction temperature along the reaction flow path.
