[0049] Several gasoline fuels were prepared by blending gasoline feedstock selected from one or more of alkylate, desulfirized catalytically cracked gasoline, dehexanizer bottoms, dehexanizer overheads, heavy straight run gasoline, light straight run gasoline, an aromatic saturated gasoline stream, hydrocracker topper light naphtha and butane. The catalytically cracked gasoline feedstock was desulfurized using technology licensed from Catalytic Distillation Technologies under one or more of U.S. Pat. Nos. 5,510,568; 5,595,634; 5,597,476 and 5,807,477 and Canadian published application 2,178,612. MTBE in an amount of about 12% by volume also was blended into the gasoline fuel. The blended gasoline fuels were all found to be in compliance with EPA regulations.
[0050] The blended gasoline fuels exhibited the following properties:
