Problems solved by technology

However, the use of a single ethanol additive has the following disadvantages: poor vaporization performance of ethanol gasoline, low calorific value, reduced power, high fuel consumption, high vapor pressure, air lock flameout in hot weather, poor storage performance, etc. When ethanol gasoline When blending with gasoline reaches 10%, it will also corrode copper

Abstract

The present invention relates to hydrocarbon containing fuel, and is especially one kind of composite gasoline additive and its preparation process. The composite gasoline additive consists of diisopropyl ether 60-70 wt% and ethanol 30-40 wt%. The composite gasoline additive has the functions of promoting combustion, eliminating carbon deposit, reducing tail gas and raising fuel oil utilizing rate greatly. The preparation process is simple and feasible.

Description

technical field [0001] The invention relates to the field of hydrocarbon-containing fuels, in particular to a composite gasoline additive and a preparation method thereof. Background technique [0002] Since the promotion of unleaded gasoline, methyl tert-butyl ether (MTBE), as a substitute for lead salts such as tetraethyl lead, has been widely used as a gasoline additive in many countries in the world. However, MTBE has a strong smell, causing dyspnea, wheezing, dizziness, headache, insomnia, bloodshot eyes and skin rashes and other allergic symptoms, and has the potential to cause cancer, and the leaked MTBE has caused serious pollution to groundwater resources. At present, there are also many countries that use ethanol as a gasoline additive. In my country's Heilongjiang, Jilin, Liaoning, Henan, Anhui and other provinces, ethanol is also being used as an additive for gasoline. However, the use of a single ethanol additive has the following disadvantages: poor vaporizati...
