LEAD-FREE GASOLINE AND BASE MATERIAL OF GASOLINE USED FOR LEAD-FREE GASOLINE

摘要

PROBLEM TO BE SOLVED: To provide a lead-free gasoline less in sulfur content and low in vapor pressure, and to provide a gasoline base material optimum as a base material of the lead-free gasoline.;SOLUTION: The lead-free gasoline, which is composed of a base material of catalytically reformed gasoline of 30-60 vol.%, a base material of fluid catalytic cracked gasoline of 0-70 vol.% and a desulfurized naphtha of 0-40 vol.%, has the amount of distillate up to 70°C of 26-40 vol.%, the Reid vapor pressure of 60 kPa or below, the Research octane number of 89-96 and the sulfur content of 10 ppm or below. The desulfurized naphtha is a desulfurized light naphtha.;COPYRIGHT: (C)2010,JPO&INPIT
