Abstract
Methods and apparatus that are used in an alkylation reactor system for adding low purity isopentane to alkylation reactor feed to block formation of isopentane, resulting in high incremental isopentane conversion and minimal octane and C5+ yield loss, and low acid consumption from C6+ isoparaffins with superior yields.
