Abstract
The invention provides an efficient environment-friendly modified alcohol-based composite fuel and a preparation method thereof, and relates to the technical field of environment-friendly fuels. The efficient environment-friendly modified alcohol-based composite fuel provided by the invention is prepared from the following raw materials in percentage by mass: 10 to 30 percent of n-pentane, 10 to 20 percent of methyl tert-butyl ether, 20 to 30 percent of octane, 10 to 20 percent of o-xylene, 10 to 20 percent of m-xylene, 5 to 10 percent of 1, 2, 3-trimethylbenzene, 5 to 33 percent of methanol, 0.2 percent of dimethylacetamide, 0.2 percent of isopropyl nitrate, 0.2 percent of ethylene glycol monomethyl ether, 0.2 percent of diisopropyl ether and 0.2 percent of fatty alcohol. 0.2% of lauryl alcohol and 0.8% of polybasic crude alcohol. The efficient environment-friendly modified alcohol-based composite fuel provided by the invention has excellent stability at a low temperature (-40 DEG C, one month) and is not easy to layer.
Description
technical field [0001] The invention relates to the technical field of environment-friendly fuels, in particular to a high-efficiency environment-friendly modified alcohol-based composite fuel and a preparation method thereof. Background technique [0002] Alcohol-based fuels are fuels mainly configured with alcohols (such as methanol, ethanol, butanol, etc.). Methanol-based fuel has a wide range of sources, the price is much lower than that of natural gas, gasoline and diesel, and the pollutants produced during combustion are lower than those of coal-fired boilers. In the face of the exhaustion of fossil energy, alcohol-based fuel is the most potential new alternative energy source, which is favored by enterprises and organizations all over the world. [0003] However, methanol-based fuels have also exposed some defects in the actual application process. Currently, methanol-based fuels on the market generally have the problem of poor low temperature stability. SUMMARY OF...
