Methanol fuel modifier, denatured methanol fuel and denatured methanol composite fuel, and preparation methods thereof

Abstract

The invention provides a methanol fuel modifier, a denatured methanol fuel and a denatured methanol composite fuel, and preparation methods thereof, and relates to the technical field of fuel energy.The methanol fuel modifier is mainly prepared from methyl tert-butyl ether, isopropyl acetate, n-butyl alcohol, isobutyl alcohol, cyclohexylamine, isopropyl ether, p-benzylaminophenol and other raw materials through synergistic cooperation. The methanol fuel modifier can be used for well modifying methanol; and the physical and chemical properties of the methanol fuel modifier are very similar tothe original physical and chemical properties of gasoline, the methanol fuel modifier can be mixed with gasoline in an unlimited proportion or used independently, and the methanol fuel modifier greatly promotes the development of methanol as an efficient clean fuel. The invention also provides the denatured methanol fuel and the denatured methanol composite fuel containing the methanol fuel modifier.

Description

technical field [0001] The invention relates to the technical field of methanol fuel, in particular to a methanol fuel modifier, denatured methanol fuel, denatured methanol composite fuel and a preparation method thereof. Background technique [0002] In recent years, with the increase of domestic motor vehicle ownership, the market demand for various fuels such as gasoline and diesel has increased significantly. But at the same time, what cannot be ignored is that the shortage of petroleum resources is becoming more and more prominent, as well as the environmental pollution caused by inhalable particulate matter, hydrocarbons, carbon monoxide, nitrogen oxides, sulfur oxides and other substances formed by the combustion of gasoline, diesel and other fuels. The pollution problem is getting worse. To this end, my country has vigorously adjusted its energy structure and adopted various measures to save fuel and reduce consumption, including actively seeking alternative fuels f...

AI Technical Summary

Problems solved by technology

Although methanol gasoline can replace traditional gasoline, there are still some problems. For example, the added co-solvent and various functional additives and gasoline components (gasoline is a mixture of more than 200 monomer components) have internal self-excitation. Reaction, the physical and chemical properties of the mixed fuel are quite different from the original physical and chemical properties of gasoline, mainly reflected in the corrosion, swelling, stability of methanol gasoline, cleanliness and other aspects that cannot be completely resolved; poor matching with gasoline engines, Mainly reflected in the impact of power performance, energy consumption and combustion performance, the formation and control of conventional pollutants and unconventional pollutants, etc.; poor versatility, mainly reflected in the inability to flexibly adjust the ratio and compatibility with traditional fuel facilities, etc.

The above problems have hindered the development of methanol as an efficient and clean fuel for vehicles to varying degrees.
