Methanol gasoline heat value agent

Abstract

The invention relates to a methanol gasoline heat value agent, belonging to the field of alcohol gasoline alternative fuel additives, and comprising the following components by weight percent: 2 percent to 4 percent of combustion catalyst, 2 percent to 4 percent of eduction agent, 83 percent to 90 percent of methanol heat value agent and 5 percent o 9 percent of gasoline heat value agent. The invention has the advantages of simple preparation, low cost, wide sources and the like, emphasizes on solving the problem that power of an engine is influenced by the descending of the heat value of methanol gasoline, and changes the difficulty of cold start of the methanol gasoline. Through a bench and road test, the use performance of the methanol gasoline after adding the heat value agent is close to burning commercial gasoline, is superior to the methanol gasoline of the same grade without adding the heat value agent, and the methanol gasoline after adding the heat value agent has equal oil consumption and power of agent with the burning commercial gasoline, better cold starting performance and acceleration quality than the commercial gasoline and lower pollution discharge than the commercial gasoline. The heat value agent has obvious effects on enhancing the heat value of the methanol gasoline and the power of the engine and easy cold start, and opens up a new path for all-round popularization with high ratio and large area of the methanol gasoline.

Description

technical field [0001] The invention relates to a methanol gasoline calorific value agent, which belongs to the field of alcohol ether substitute fuel additives. Background technique [0002] Oil prices have been rising all the way, and the world is calling for oil shortages. All countries are turning their attention to alternative fuels for vehicles. Methanol gasoline is the most researched, the most widely sourced, and the most economical automobile fuel substitute. my country has promulgated fuel methanol standards, and the national standards for methanol gasoline are also being formulated and will be promulgated and implemented in the near future. The legalization of methanol gasoline has further promoted the development of methanol gasoline. However, technically, the biggest problem restricting methanol gasoline is the low calorific value of methanol, which affects the power of automobile engines, which limits the high proportion of methanol blended. The lower calori...

Problems solved by technology

For example, in the two invention patents of "a kind of methanol fuel for vehicles" of the notification number CN1326979C and "synthetic environmental protection methanol fuel" of the notification number CN100453625C, it is disclosed to add 3-8% mixed benzene respectively in order to improve the calorific value and power. And 10-40 benzene or toluene, xylene, although play a certain role in increasing the calorific value, benzene is a highly toxic carcinogen, which is strictly restricted in gasoline; as the "gasoline alcohol" invention patent of the notification number CN1314452A , discloses that NaoH (strong alkali sodium hydroxide) is contained in the denaturant, which can effectively increase the heating value of methanol gasoline, but the strong alkalinity of sodium metal oxide in the combustion product and the residue produced under the condition of no extraction agent are harmful to Metals cause corrosion and wear; another example is the invention patent of "high-performance and high-content methanol gasoline" with the publication number CN1727452A. Kerosene and anhydrous hydrazine are used in the power enhancer. Although the power has a positive effect, the kerosene will make the combustion of gasoline The characteristics become worse, anhydrous hydrazine is highly toxic, and it is harmful to people and the environment when added to methanol gasoline; another example is the invention patent of "a preparation method for M80-M90, E80-E90 alcohol-based vehicle fuel additives" with the publication number CN1916126A, It is disclosed that 5-10% of the energizer in the additive is tetrahydrofuran, 8-hydroxyquinoline, and methyl ethyl ketone peroxide, which play an important role in increasing the calorific value and improving the engine power, but these are expensive fine The price of chemicals is more than tens of thousands of yuan per ton, and the cost is relatively high
