Abstract
A process for producing an alkylate having a low Reid vapor pressure, the process including: contacting a C-containing hydrocarbon stream with a mixture of isopentane and isobutane in the presence of an acid catalyst in an alkylation reactor to form a dilute alkylate product, wherein the C-containing hydrocarbon stream includes at least one of oligomers of Cto Colefins and a dilute alkylate produced by contacting an isoparaffin with at least one of Cto Colefins and oligomers of Cto Colefins; fractionating the dilute alkylate product to form an isobutane-rich fraction, a n-butane-rich fraction, a fraction containing isopentane, and an alkylate product having a Reid vapor pressure less than 0.35 bar (5 psi); recycling at least a portion of the fraction containing isopentane to the alkylation reactor.
