Additive for improving dynamic property of methanol gasoline

Abstract

The invention discloses an additive for improving dynamic property of methanol gasoline. The additive is prepared from the following raw materials by weight percent: 18.0-31.0% of 2,2-diisopropyl-1,3-dioxolane, 15.0-29.5% of aminoacetaldehyde diethyl acetal, 15.0-24.5% of 1,3-cyclooctadiene, 13.0-24.0% of 1-cyanoethyl-2-ethyl-4-methylimidazole, 10.0-20.5% of 5-methyl-2-heptylene-4-ketone and 9.0-19.5% of 1,4-bi(phenyl acetic diacyl) benzene in a manner of evenly stirring and mixing at normal temperature. According to the additive disclosed by the invention, the improvement effect on heat value power of the methanol gasoline is significant, and the dynamic properties such as acceleration are obviously superior to those of the same mark of methanol gasoline by adding 0.3-1.0% of methanol gasoline into the common methanol gasoline.

Description

technical field [0001] The invention belongs to the technical field of methanol replacing vehicle fuel, and relates to a methanol gasoline additive, in particular to an additive for improving the power performance of methanol gasoline. Background technique [0002] With the increasing shortage of world oil resources and the increasing air pollution, the energy crisis has become the bottleneck of economic development, and new alternative fuels have attracted the attention of all parties. my country's dependence on foreign oil has exceeded 53%, and energy and environmental issues restrict the rapid development of my country's economy. my country is a country that is poor in oil and gas but relatively rich in coal. It is entirely feasible to replace part of the oil with coal to produce methanol. Using methanol as a substitute fuel for internal combustion engines is an effective way to protect the environment and use energy rationally. [0003] According to the National Develop...

Problems solved by technology

[0005] In order to solve the problem of low calorific value and lack of power of methanol fuel, many achievements or patents have emerged in recent years, such as CN 102260548A and CN 101724471A, which use coal tar and anhydrous hydrazine, coal tar colloid, ash, etc. High content of harmful substances, poor combustion characteristics, anhydrous hydrazine is highly toxic, and it is harmful to humans and the environment when added to methanol gasoline

Some calorific value catalysts have used heavy metal salts, such as CN 101029258A (KMnO 4 ), CN 101343574A (ferrocene), CN 102146304A (KNO 3 ), CN 101372636A (MMT), these organometallic salts belong to the restricted use of vehicle fuel

There are also various catalytic methods, such as in CN 101985569A and CN 101643673A, the power accelerators are nitro compounds such as nitrates and nitrobenzene, and fuel catalysts and calorific value agents in CN 101619250A use nitrates, carbonic acid Salt, halides are used as elicitors, these reagents will cause the intensification of electrochemical reactions
