Biological alcohol-based light fuel flash point improver

Abstract

The invention discloses a biological alcohol-based light fuel flash point improver, which is composed of 19.5 to 22.0% of a component capable of increasing intermolecular force, 23.0 to 26.0% of a component capable of increasing the boiling point, 21.0 to 22.0% of a component capable of increasing density, 21.0 to 22.0% of a component capable of reducing saturated vapor pressure, and 9.0 to 12.5% of a component having surface with film forming and flame retardantion. The five functional components can be stirred evenly under normal temperature, and the biological alcohol-based light fuel flash point improver product can be obtained. The improver can increase the intermolecular force, and improves the boiling point of an oil-alcohol system, increases density of the oil-alcohol system, reduces saturated vapor pressure of the oil-alcohol system, forms a flame retardant film on the surface of oil-alcohol system, blocks the spontaneous combustion of methanol, improves the non corrosive performance of the flash point of the oil-alcohol system, has the characteristics of biodegradability, no harmful components and no secondary pollution to the environment, and effectively solves the technical problems of low flash point, large transportation and storage safety hazard of light fuel.

Description

technical field [0001] The invention relates to the field of alcohol substitute fuels, in particular to a bioalcohol-based light fuel flash point enhancer. Background technique [0002] For a long time, gasoline and diesel have been the main fuels for various types of motor vehicles. This usage pattern is increasingly restricted by serious environmental pollution and increasingly scarce resources. In order to improve this dilemma, a variety of energy alternatives have been adopted at home and abroad. However, if these alternatives are to be popularized on a large scale, there are serious defects. In addition, diesel engines contain a large number of particles in their exhaust, these particles are mainly composed of black carbonaceous substances, the sedimentation rate is very low, and can be suspended in the atmosphere for a long time, causing serious smog, which has caused great harm to human health. great harm. [0003] Alcohol fuel, as a clean, cheap and efficient alter...

Problems solved by technology

[0005] In recent years, there have been many patents on so-called environmentally friendly biodiesel and high-clean methanol diesel. For example, the patent number is CN101955810A, which discloses a "green biodiesel", and the patent number is CN101205487A, which discloses a "methanol diesel". CN102134516A discloses a "high-clean methanol diesel and its preparation method" and the patent number is CN101709234A, which discloses a "methanol diesel composite additive and its preparation method", but the above-mentioned patents dare not mention the above-mentioned For the flash point temperature of the embodiment, some patents mentioned the flash point enhancer, but did not explain its principle of action, nor did it mention the actual flash point data. This is nothing more than grandstanding, and it still does not solve the methanol diesel flash point at all. point low problem

The patent number is CN101886000A, which discloses a "preparation method of methanol diesel oil". The flash points of the described examples are all between 45°C and 55°C, but the oil production process is cumbersome, and the required equipment is very demanding. Conditions are strictly controlled, which is not conducive to large-scale production and use
