Abstract

The invention relates to a methanol fuel additive for cold plateau region. The additive is prepped by adding 3-20 wt.% of an oxidant hydrogen peroxide with mass concentration of 30%, 1-6% of an antifreeze, 0.2-3% of an antioxidant antigum agent 2,6-butylated hydroxytoluene, 0.05-0.6% of a metal passivator N,N-bis(salicylidene)-1,2-propanediamine, 0.008-0.06% of a detergent dispersant, 1-6% of a preservative and 1-20% of a emulsifier into 10-83.742% of aqueous solution, mixing evenly by pump circulation, then successively adding 3-20% of naphtha, 3-10% of toluene, 2-10% of xylene, 2-10% of C5H12-C7H16 in weight ratio of 1:1, and mixing homogeneously by pump circulation. At the same time, the invention also discloses a ratio and a preparation method of a methanol fuel containing the methanol fuel additive for cold plateau region. The methanol fuel additive for cold plateau region provided by the invention has good and stable performance, and solves the problems of low temperature fluidity, high altitude hypoxia burning property, low sulfur, low nitrogen and dynamic stability.

Description

technical field [0001] The invention relates to the technical field of fuel chemical industry, in particular to a methanol fuel additive in plateau alpine regions and methanol fuel containing the additive. Background technique [0002] The world today is facing two major problems: one is the oil energy crisis. The world's oil reserves are limited, and with economic development, oil consumption is increasing year by year. The second is environmental pollution. When petroleum products are used as fuel, the carbon oxides, hydrocarbons, nitrogen oxides, sulfur oxides contained in the exhaust gas after combustion and various carcinogens contained in petroleum seriously threaten people's health. Therefore, actively seeking and developing clean energy has become a top priority for all countries, compared to electric energy, liquid hydrogen, liquefied petroleum gas, natural gas, nuclear energy, etc. As a new type of clean energy, alcohol-based fuel not only has multi-channel synt...
