Sub-Product

The Alkylation Process combines light iso-Paraffins, most commonly Isobutane, with C₃–C₄ Olefins, to produce a mixture of higher molecular weight iso-Paraffins (i.e., Alkylate). Alkylate Product is a Mixture of Branched Paraffinic Hydrocarbons of Gasoline boiling range (mostly Isoheptane and Isooctane). Alkylate has a Motor Octane (MON) of 90-95 and a Research Octane (RON) of 93-98. Because of its high Octane and low vapor pressure, Alkylate is considered an excellent Blending Component for Gasoline.^[1],[2],[3]
