Problems solved by technology

[0004] At present, there are many kinds of alcohol-based liquid fuels popular in the market, and there are still some problems to varying degrees: single component, low calorific value, high price, complicated preparation process, special supporting equipment is required, and some also contain high Contaminated substances have a certain gap with traditional fuels in terms of combustion speed, gasification calorific value, mutual solubility, explosive acceleration performance, etc., and cannot completely replace gasoline, which limits large-scale promotion
For example, the invention patent application with the application number CN03152748.5 discloses a methanol gasoline for vehicles. The additives are simply mixed with hydrocarbon fuels, the additive components are too single, the mixing effect is poor, the calorific value is low, and the energy consumption is large, which limits its popularization and use

Description

technical field [0001] The invention belongs to the technical field of alcohol-based liquid fuel, and in particular relates to a high-energy alcohol-based liquid fuel and a preparation method thereof. Background technique [0002] In recent years, the gradual depletion of energy and resources, the shortage of petroleum resources, the continuous growth of industrialization and the widespread use of vehicles have offset the technological progress made in the control of exhaust emissions. In cities, 78% of carbon monoxide, 45% of nitrogen oxides, and 37% of volatile organic compounds are harmful substances emitted by a large amount of fossil fuel combustion, which seriously pollute the environment. Therefore, it is extremely urgent to develop resource-rich, environmentally friendly and economically viable alternatives to fossil fuels. At present, alternative fuels mainly include: first, coal-based alternative liquid fuels, including methanol, dimethyl ether, and synthetic oil;...
