Abstract

The invention relates to high-cleanness blended gasoline and its preparation method. The blended gasoline is characterized by comprising the following components by weight: 35-45% of arene; 25-35% of naphtha; 6-10% of MTBE (methyl tert-butyl ether); 1-3% of an antiknock additive; 6-10% of heavy C5; and 10-15% of light C5. Specifically, the antiknock additive is prepared by the steps of: adding raw material 1#, raw material 2# and raw material 3# uniformly into a small tank according to a batching ratio, conducting stirring and blending for 2-3h, then leaving the mixture to stand for 8h. In the gasoline blending process, raw materials are mixed according to the ratio of the above formula in a blending tank for blending till blended uniformly, and then the mixture is left to stand for 8h. The blended gasoline of the invention has the advantages of good ignition startup performance, high flame resistance, strong stability, good intersolubility, strong driving force, good environmental protection property, and advanced blending technology. 6-8h is needed for refining a tank of gasoline in an oil refinery, while only 2h is needed for blending a tank of gasoline by the method of the invention. The antiknock additive in the invention can effectively enhance gasoline quality and RON (research octane number), reduce or eliminate peroxides.

Description

Technical field: [0001] The invention relates to a blended gasoline, in particular to a high-clean blended gasoline, and also relates to a preparation method of the blended gasoline. Background technique: [0002] Most of the 90#, 93#, and 97# gasoline currently available on the market are component oils obtained through distillation and separation of crude oil in refineries, processed through complex production processes, and then blended into gasoline. The process produces pollution, waste, waste gas, and waste water, and the cost is high, the land occupation is large, and the yield is low, which cannot meet the current market demand. However, in addition to being used as chemical raw materials, some of its associated resources can be used as gasoline blending components and have not been utilized. Contents of the invention [0003] The purpose of the present invention is to provide a kind of high-clean blended gasoline that meets the relevant national standards by usin...
