Problems solved by technology

[0003] Due to the difference in physical and chemical properties between methanol and commonly used gasoline, the high-proportion compounded methanol gasoline sold in the market now has poor miscibility, easy knocking, unsuitable saturated vapor pressure, easy air lock, poor power, etc. during the deployment and use process. A series of problems, when methanol contains a small amount of water, it will produce certain chemical reactions, and even corrode the parts, and methanol gasoline and petroleum gasoline are not easy to mix, which brings inconvenience to users. The high proportion of methanol gasoline with petroleum gasoline performance has certain practical significance

Abstract

The monophase catalyzed methanol gasoline is mixture of 99.5 % purity methaol 20-80 weight portions, gasoline 10-75 weight portions, methyl tert-butyl ether 3-8 weight portions, epoxidized soybean oil 0.1-0.5 weight portions, dibutyl phthalate 0.1-0.5 weight portions, diallyl phthalate 0.1-0.5 weight portions, acetone 2-5 weight portions, and ethyl acetate 2-5 weight portions. It has improved cold startability and accelerating ability, raised octane number, improved octane number distribution, excellent combustibility, monophase catalyzing property and other advantages.

Description

technical field [0001] The invention relates to methanol gasoline, in particular to a single-phase catalytic high-proportion methanol gasoline. Background technique [0002] The world's energy reserves are becoming increasingly scarce, and energy issues have attracted great attention from all countries in the world. Therefore, seeking new alternative energy has become a global issue. my country is a country that is poor in oil and gas but relatively rich in coal resources. Therefore, using coal to produce methanol, and then using methanol as the main raw material supplemented with corresponding chemical additives to prepare methanol gasoline with performance comparable to that of petroleum gasoline is an energy source in line with my country's national conditions. As one of the research and development routes, methanol gasoline has broad market prospects as a cheap and clean vehicle fuel. [0003] Due to the difference in physical and chemical properties between methanol and...
