Problems solved by technology

The main reason why this study uses the distillation range experiment to predict the saturated vapor pressure is that the Reid method for domestic oil product testing is quite complicated, and the measurement results are also greatly affected by human factors, and the measurement error often reaches more than 5%. It is not suitable for large-scale research needs, which limits the study of saturated vapor pressure to a certain extent

Abstract

The invention provides a composite additive for reducing the saturated vapor pressure of methanol gasoline. Ethanol, allyl alcohol, toluene, nitromethane, cyclohexanone, ethylenediamine, xylene, 1,2-propylene glycol, isoamyl alcohol and the like are evenly mixed at normal temperature and normal pressure to prepare the composite additive. The composite additive is mixed with industrial methanol to produce denatured alcohol, and the denatured alcohol is mixed with base oil to produce finished products of the methanol gasoline. The composite additive has the advantages of effectively reducing the saturated vapor pressure of the methanol gasoline and eliminating the high-temperature air resistance phenomenon during the use of the methanol gasoline.

Description

technical field [0001] The invention relates to a fuel oil additive for vehicles, in particular to a methanol gasoline additive. The additive of the invention can effectively reduce the saturated vapor pressure of the methanol gasoline to eliminate the air lock phenomenon. Background technique [0002] As international crude oil prices continue to run at high levels, the implementation of energy diversification strategies is an important choice made by governments around the world. my country is a country that is short of oil, less gas, and relatively rich in coal. Reasonable, efficient, energy-saving and safe development of coal-based alternative fuels is the only way out for my country's energy development. As an alternative fuel, methanol fuel is gradually developing in my country. clear. [0003] my country has made great achievements in the promotion and demonstration of methanol gasoline, especially low-proportion methanol gasoline. However, in the process of practical...
