Ether-based fuel

Abstract

The invention relates to a novel clean fuel, in particular to a clean ether-based fuel. The ether-based fuel comprises dimethyl ether, methanol and 2,6-di-tert-butyl-p-cresol. More particularly, the ether-based fuel can be formed just from dimethyl ether, methanol and 2,6-di-tert-butyl-p-cresol. The ether-based fuel provided by the invention can be used for automobiles and other transport vehicles or power equipment using gasoline engines instead of gasoline. The invention also relates to a mixed fuel comprising the ether-based fuel and gasoline.

Description

technical field [0001] The invention relates to a new type of clean fuel, in particular, a clean ether-based fuel. The ether-based fuel contains dimethyl ether, methanol and 2,6-di-tert-butyl-p-cresol. More specifically, the ether-based fuel may consist solely of dimethyl ether, methanol, and 2,6-di-tert-butyl-p-cresol. The invention also relates to an ether-based fuel comprising dimethyl ether, methanol and 2,6-di-tert-butyl-p-cresol, and at least one additive selected from water, castor oil and succinimide. The present invention also relates to blended fuels comprising the ether-based fuels of the present invention and gasoline. Background technique [0002] As we all know, petroleum, as a non-renewable resource, plays an indispensable role in a country's social life and national defense construction. With the continuous improvement of people's living standards in our country, cars have gradually entered the families of ordinary people. For example, Beijing has now ent...

Problems solved by technology

[0008] Although the standards for methanol gasoline have been promulgated and implemented, there are still some problems with methanol gasoline due to the material characteristics of methanol: first, the volatility of methanol relative to gasoline components is poor, resulting in difficulties in cold starting and insufficient combustion of engines using methanol gasoline; Methanol and gasoline have poor miscibility, short shelf life, and easy to deteriorate and stratify; third, the substitution ratio is low (that is, about 1.6-1.7 parts of methanol needs to be used to replace 1 part of gasoline), and fourth, if the engine structure is not changed, methanol gasoline is now Insufficient combustion and lack of power in some engines
