METHOD FOR JOINT PRODUCTION OF LOW OCTANE NUMBER GASOLINE AND HIGH OCTANE NUMBER GASOLINE.

摘要

A method for joint production of low octane number gasoline and high octane number gasoline. During oil rectification or light oil rectification, distillation points of distillates are finely divided, and temperature interval for extraction of fractions is shortened, high content of low octane number components and high content of high octane number components in C6-C12 (which may be extended to C5-C14, if necessary) are respectively extracted, and then the low octane number components are combined into a compression-ignition gasoline product with a low octane number, and the high octane number components are combined into a gasoline product with a high octane number. The remaining fractions are respectively added to the gasoline product with a low octane number or the gasoline product with a high octane number according to the octane number. The gasoline product with a low octane number is used in a compression-ignition gasoline engine, and the gasoline product with a high octane number is used in a spark ignition gasoline engine.
