Advanced ethanol gasoline for treating haze and preparation method thereof

Abstract

The invention provides advanced ethanol gasoline for treating haze and a preparation method thereof. The advanced ethanol gasoline for treating the haze is prepared from the following components in percentage by weight: 20 to 22 percent of ethyl alcohol, 20 to 30 percent of alkylated gasoline, 15 to 20 percent of naphtha, 17 to 25 percent of aromatic hydrocarbon, 20 to 25 percent of alkene and 0.141 to 0.16 percent of an MG2000 gasoline promoter. The preparation method comprises the following steps: (1) weighing the ethyl alcohol, the alkylated gasoline, the naphtha, the aromatic hydrocarbon and the alkene in proportion, and then mixing uniformly to obtain a mixture; and (2) adding the MG2000 gasoline promoter into the mixture of the step (1) under a dark condition, and mixing uniformly toobtain the advanced ethanol gasoline. The ethanol gasoline is environment-friendly, and does not contain high-toxicity carcinogenic substances, such as teraethyl lead, a manganese agent, methyl tert-butyl ether and methyl alcohol; and the aromatic hydrocarbon and the alkene can be fully combusted to improve the combustion efficiency.

Description

technical field [0001] The invention belongs to the technical field of gasoline, and in particular relates to a high-grade ethanol gasoline for treating smog and a preparation method thereof. Background technique [0002] At present, my country has become the third largest producer and application country of biofuel ethanol in the world after Brazil and the United States. In 2010, the national fuel ethanol production reached 1.7 million tons. At present, 10 provinces and cities in my country are promoting the use of ethanol gasoline as pilot projects for ethanol gasoline; among them, all gas stations in 5 provinces of Heilongjiang, Jilin, Liaoning, Henan, and Anhui are fully promoting the use of ethanol gasoline; Hubei, Shandong, Hebei, Jiangsu, Parts of the five provinces in Guangxi have also promoted the use of ethanol gasoline. [0003] However, the ethanol gasoline produced in my country has the following problems: firstly, the user feels that the power is insufficient, ...

AI Technical Summary

Problems solved by technology

[0003] However, the ethanol gasoline produced in my country has the following problems: First, the user feels that the power is insufficient, the fuel consumption increases, and the fuel in each tank runs less than 100 kilometers, and air lock, flameout, knocking, etc.

In addition, the increase of the accumulation of the engine makes the atomization of the fuel injector poor, which causes the combustion efficiency of ethanol gasoline to decrease and the fuel consumption to increase. The induction period of ethanol gasoline only reaches 200 minutes, so the performance is very unstable

The most important problem is that ordinary ethanol gasoline cannot combine aromatics and olefins in gasoline

In this way, ordinary ethanol gasoline leads to low combustion efficiency, wastes 20% to 30% of oil products, runs more than 100 kilometers less per tank of fuel, and reduces exhaust emissions by 30% compared to gasoline added with MTBE. It still causes harm to the atmosphere and produces smog problems.
