Energy-saving environment-protective methanol gasoline for vehicle and preparation thereof

Abstract

The invention relates to an energy-saving and environment-friendly vehicle methanol gasoline and a preparation method thereof, belonging to the technical field of alternative energy sources. The vehicle methanol gasoline is prepared by the following materials by weight percentage: 30-88.5% of white gasoline component oil, 10-55% of methanol and 1.5-15% of composite additive; the composite additive is composed of the following components: 60-77.5% of latent solvent, 17-30% of heat value enriching substance, 0.08-1.3% of power synergistic agent, 3.5-10% of homogeneous catalysis combustion improver, 0.6-3.0% of corrosion and swelling inhibitor and 1.5-3.5% of vapor pressure regulator, after being evenly mixed, the materials are added into 10-55% of methanol, after being slightly stirred, the mixture is filled in 30-85.5% of white gasoline, evenly stirred and is subject to static reaction for 4-8 hours. The methanol gasoline can effectively solve the technical difficult problems of power reduction, high gasoline consumption, corrosiveness, swelling, difficult cold start, high-temperature air resistance, and the like, when the content of methanol gasoline is 10-55%; the vehicle methanol gasoline can be directly used on automobiles, while engines do not need to be modified; the vehicle methanol gasoline can also be mixed or interchanged with white gasoline and ethanol gasoline for application. The invention has the advantages of easily available raw materials, low cost, simple preparation technique and significant energy-saving benefit, and can greatly reduce tail gas pollutant emission.

Description

Technical field: [0001] The invention relates to methanol gasoline for energy-saving and environment-friendly vehicles and a preparation method thereof, which is obtained by adding methanol and a composite additive composed of a cosolvent, a calorific value extender, a corrosion swelling inhibitor, a vapor pressure regulator, etc. to unleaded gasoline. Energy-saving and environmentally friendly vehicle fuel. Background technique: [0002] With the rapid development of the world economy, the consumption of petroleum resources is increasing day by day, and the environmental pollution is becoming more and more serious, which seriously threatens the sustainable development of human society. In order to protect the "global village" of human beings, protect human health, and maintain ecological balance, energy and environmental issues have become two major issues of concern to the world after mankind entered the 21st century. Many countries have begun to research, develop and uti...
