Large-proportion methanol catalytic combustion agent

Abstract

The invention relates to a large-proportion methanol catalytic combustion agent, which belongs to the field of alcohol ether fuel alternative oil additives, and comprises 3-50% of initiator, 4-90% of oxidizer, 1-20% of activating agent, 0.5-10% of cleaning agent, and 2-30% of friction-reducing agent. The large-proportion methanol catalytic combustion agent has the effects of overcoming the cold start of methanol and the difficult self-ignition, and improving the burning rate of the methanol, the power of an engine and the oil conservation. Due to the strong catalytic oxidation and decomposition capability of the catalytic combustion agent, the large-proportion methanol catalytic combustion agent can promote the fast and full combustion of the methanol, improve the carbon deposition of a combustion chamber, play roles of cleaning and lubricating the engine, reduce the abrasion of the engine caused by the combustion of the methanol and reduce the emission of combustion waste gas. The large-proportion methanol catalytic combustion agent has the comprehensive catalytic function and the synergy, and can effectively inhibit metal corrosion and rubber swelling, further enhance and improve the large-proportion methanol catalytic combustion effect, and open a new way of the large-proportion methanol catalytic combustion technology for popularization and application of large-proportion methanol fuels: methanol gasoline, microemulsion alcohol gasoline, methanol bio-gasoline, methanol diesel, microemulsion alcohol diesel, methanol bio-diesel and alcohol-based fuel.

Description

1. Technical field [0001] The invention belongs to an alcohol ether fuel oil substitute additive, in particular to a large-proportion methanol catalytic combustion agent. 2. Background technology [0002] The ten key energy-saving projects of the country's "Eleventh Five-Year Plan" clearly pointed out: to develop alcohol-ether fuels instead of oil, and to promote a large proportion of methanol catalytic combustion technology.... To promote the large-scale methanol catalytic combustion technology, the key lies in the development of a dedicated high-efficiency large-scale methanol catalytic combustion agent. This is still a brand-new research and development field at home and abroad, and it is still in its infancy. Similar patents and papers have not yet appeared. and literature reports. Although there is no special catalytic combustion agent technology for a large proportion of methanol, there have been some patents on improving the combustion efficiency of methanol fuel. I...

Problems solved by technology

In the two invention patents of "a kind of methanol fuel for vehicles" of notification number CN1326979C and "synthetic environmental protection methanol fuel" of notification number CN100453625C, it is disclosed that aromatics such as mixed benzene and benzene are added respectively for improving combustibility. The thermal efficiency aspect of motor has produced important effect, but benzene is highly toxic carcinogen, has been strictly restricted in the national standard of gasoline; In the invention patents, it is disclosed that ferrocene is added to improve the combustion efficiency of methanol. Ferrocene has a good effect on improving the thermal performance of the engine, but these metal compounds will cause secondary pollution of heavy metal particle emissions. National standards for methanol gasoline and unleaded gasoline have all been restricted, and it is stipulated that no artificial iron-containing metal additives can be added; another example is the "gasoline alcohol" invention patent of the notification number CN1314452A, which discloses that the denaturant contains strong alkali sodium hydroxide Components can effectively improve the combustion performance of the engine, but the alkali metal in the combustion product will cause corrosion to the engine; another example is the invention patent of "high-performance and high-content methanol gasoline" with the notification number CN100491506C, which discloses a power enhancer for improving combustion The use of kerosene and anhydrous hydrazine can promote power and combustion efficiency, and can effectively increase engine power, but anhydrous hydrazine is highly toxic and highly corrosive, and adding it to methanol gasoline is harmful to humans and the environment; another example is the bulletin number In the two invention patents of "alcohol-based liquid fuel" of CN1108358C and "alcohol-based liquid fuel" of publication number CN1667094A, it is disclosed that the calorific value and flame temperature of methanol fuel are improved, and metal compounds such as potassium permanganate are added. It has a good combustion-supporting effect on the combustion of methanol, but according to the introduction of "Chemical Dictionary", potassium permanganate will decompose immediately when it encounters methanol and acetic acid

In addition, the combustion products of potassium permanganate are corrosive to metals and harmful to the environment and people. Therefore, the use of these gray metal compounds has been strictly limited.
