Problems solved by technology

Due to the high saturated vapor pressure of methanol gasoline, air lock will be generated at high temperature, and the fuel supply cannot be normal, so that the vehicle cannot run normally.
[0004] At present, the existing methanol gasoline additives cannot be used to solve the problem in China. Due to the high saturated vapor pressure of methanol gasoline, the problem of air lock will occur at high temperature in summer, which has become a bottleneck encountered in the promotion and popularization of methanol gasoline.

Abstract

The invention relates to a mixing method capable of reducing saturated vapor pressure of a base oil of a methanol gasoline. The method is characterized in that the base oil is obtained by mixing the following raw materials in percentage by weight through a static mixer: 10-15% of solvent oil, 1-5% of dimethyl carbonate, 5-10% of reformate and 70-85% of national standard gasoline. The base oil mixing method provided by the invention has the advantages of simple formula, easiness in operation as well as convenient and feasible application. An automobile can also normally run at high temperature in summers when being filled with the methanol gasoline.

Description

technical field [0001] The invention relates to a blending method, in particular to a blending method capable of reducing the saturated vapor pressure of base oil of methanol gasoline. belongs to the field of energy. Background technique [0002] Energy is the lifeblood of a country's economy. Energy security is related to national economic security and national security. Since my country became a net oil importer in 1993, its oil imports have been soaring. Against the backdrop of the intensifying global energy crisis and the high volatility of international oil prices affected by geopolitics and emergencies, if my country's high dependence on external energy does not change, it will inevitably have a serious impact on national economic security and sustainable development. Therefore, implementing the energy substitution strategy, replacing traditional energy with new energy, replacing scarce energy with superior energy, replacing fossil energy with renewable energy, and ...
