A method of producing, from low octane naphtha, motor gasoline having balanced octane across the boiling range thereof, which gasoline consists essentially of catalytic reformate and sufficient light hydrocarbons to produce the desired gasoline vapour presure, comprises distilling said naphtha to produce a low-boiling fraction, an intermediate-boiling fraction and a high-boiling fraction, blending selected portions of each of said fractions to produce a reformer charge stream and subjecting said charge stream to catalytic reforming to produce a reformate having balanced octane across the boiling range thereof, and blending said reformate without further treatment with light hydrocarbons to produce said gasoline. By selecting different proportions of the three cuts, end-products of varying octane numbers may be produced. |
