Abstract

A method for preparing ethanol-diesel oil mixed fuel. At least one emulsifier is obtained, wherein the emulsifier is one or more than one of lauryl amine polyoxyethylene ether, polyoxyethylene fatty acid ester, polyoxyethylene fatty amine ether, polyoxyethylated castor oil, or fatty alcohol-polyoxyethylene ether. Ethanol is added into a mixture of the emulsifier and diesel oil, and an emulsification temperature of 50-80 DEG C is maintained. The percents of the components are 15-25% of the emulsifier, 60-80% of the diesel oil, and 10-20% of the ethanol. The beneficial effects of the invention are that: good emulsification and fusion of ethanol and diesel oil is realized by using the emulsifier, and the obtained ethanol-diesel oil fuel is uniform in quality and easy to combust, and has a large fuel value.

Description

technical field [0001] The invention relates to the field of energy and chemical industry, in particular to a method for preparing ethanol-diesel mixed fuel. technical background [0002] my country is a country short of oil resources. Due to the rapid development of my country's automobile industry and the acceleration of the trend of automobile diesel engines in recent years, the demand for diesel oil has greatly increased. pollution. Therefore, it is an urgent problem to be solved in our country to develop and utilize resource-rich, environment-friendly and economically feasible alternative fuels for vehicles to achieve energy saving, emission reduction and sustainable development. [0003] Ethanol is a renewable resource. Using ethanol to partially replace diesel can not only alleviate the tight supply of diesel, but also reduce the emission of environmental pollutants. Ethanol-diesel is an energy-saving and environmentally friendly fuel. The burning methods of ethanol...
