Abstract

The invention discloses component oil capable of reducing saturated vapor pressure of methanol gasoline, which is prepared from 20 to 25 percent of No.120 solvent oil, 20 to 25 percent of No.200 solvent oil, 5 to 10 percent of methylbenzene, 3 to 5 percent of dimethylbenzene, 20 to 30 percent of heavy naphtha and 20 to 25 percent of catalytic reformed gasoline. The component oil is mainly used for blending with traditional national standard No.90 and No.93 gasoline to prepare low proportional methanol gasoline with the methanol content of 10 to 30 percent, so that the positive deviation of the saturated vapor pressure of the low proportional methanol gasoline is rectified, the saturated vapor pressure of the low proportional methanol gasoline is effectively reduced, the vapor pressure is ensured to be not high when the national standard No.90 and No.93 gasoline are doped with the low proportional methanol, a 'vapor lock' phenomenon cannot happen in high temperature weather, and an engine can normally work.

Description

technical field [0001] The invention belongs to the technical field of methanol fuel for vehicles, and relates to a component oil for methanol gasoline, in particular to a component oil for methanol gasoline with a low ratio of vehicle. The component oil of the invention can effectively reduce the saturated vapor pressure of gasoline with a low proportion of methanol. Background technique [0002] The world's energy reserves are becoming increasingly scarce and environmental problems are becoming more and more serious. Energy and environmental issues have attracted great attention from all countries in the world. Therefore, seeking new clean alternative energy has become a global issue. my country's economy is developing at a high speed. At present, there are more than 70 million automobiles, and most of the oil consumed every year needs to be imported. Energy and environmental issues restrict the rapid development of my country's economy. [0003] my country is a country ...
