METHOD OF PRODUCING GASOLINE BLENDSTOCK

摘要

PROBLEM TO BE SOLVED: To provide a method of producing gasoline blendstock containing an isopentane fraction at high concentrations without using a high-pressure tank for liquefied petroleum gas.;SOLUTION: The method includes: a step of fractionally distilling a hydrocarbon oil to obtain the isopentane fraction having an isopentane content of 70 vol.% or more and a normal pentane content of 12 vol.% or less; and a step of directly mixing the isopentane fraction with a cracked gasoline fraction or a modified gasoline fraction to obtain the gasoline blendstock having an absolute vapor pressure lower than atmospheric pressure.;COPYRIGHT: (C)2012,JPO&INPIT
