Abstract

The invention relates to the filed of alcohol ether alternative fuel, in particular to stable high-performance large-proportion methanol gasoline comprising 30-87 percent of denatured methanol and 13-70 percent of denatured gasoline. The denatured methanol comprises 15-82 percent of fuel methanol, 1.5-5 percent of fatty alcohol, 1.7-9.7 percent of aliphatic ether and 0.5-1.8 percent of methanol denaturant; and the denatured gasoline comprises 7.8-50 percent of naphtha or merchantable gasoline, 1-10 percent of condensate oil, 1-5.5 percent of C5, 1-5 percent of toluene or xylene, 0.5-1.1 percent of petroleum ether or ether and 0.3-1.2 percent of gasoline denaturant. Compared with traditional methanol gasoline, the invention has superior large methanol proportion, long water-resistant stabilization period, high thermal value, strong dynamic property, cold startability, anti-air-resistance property, slow metallic corrosion and anti-swelling property of rubber, solves the six existing problems hindering the popularization and the use of the methanol gasoline for a long time and has low cost, favorable economic benefits, social benefits and environmental benefits.

Description

technical field [0001] The invention belongs to the field of automobile alcohol ether substitute fuels, in particular to a stable high-performance large-proportion methanol gasoline. Background technique [0002] With the rapid growth of the number of automobiles, gasoline resources are becoming more and more scarce, so the development and utilization of alternative fuels for automobiles is an inevitable development trend in the future. my country is rich in coal and poor in oil, and the use of coal to produce methanol as an alternative fuel for vehicles has a very broad prospect. The national standard for fuel methanol has been promulgated and officially implemented on November 1, 2009. The national standard for M85 methanol gasoline has also been promulgated and officially implemented on December 1, 2009. Therefore, methanol gasoline will have a wide market and is an extremely ideal alternative fuel for vehicles. [0003] A lot of research on methanol gasoline has been c...
