Energy-efficient ethanol gasoline and preparation method thereof

Abstract

The invention discloses energy-efficient ethanol gasoline and a preparation method thereof. The energy-efficient ethanol gasoline is prepared from components in percentage by weight as follows: 10%-15% of ethanol, 20%-30% of alkylation gasoline, 15%-20% of naphtha, 17%-25% of arene, 20%-25% of olefin and an appropriate quantity of an MG2000 gasoline accelerant. The preparation method comprises steps as follows: 1), ethanol, alkylation gasoline, naphtha, arene and olefin are weighed in the ratio and mixed uniformly, and a mixture is obtained; 2), under the dark condition, the MG2000 gasoline accelerant is added to the mixture obtained in the step 1) in the ratio and mixed uniformly. The ethanol gasoline is not only environmentally friendly, but also can realize sufficient burning of arene and olefin, and the burning efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of gasoline, and in particular relates to a high-efficiency energy-saving ethanol gasoline 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.
