Problems solved by technology

However, the vast majority of methanol and fossil gasoline are simply blended or only part of the co-solvent is added, and the selected methanol raw material is not denatured, thus exposing a series of problems when methanol and fossil gasoline are deployed and used (such as Low combustion efficiency, high fuel consumption, power drop, low-temperature cold start, stratification, emulsification and exhaust emissions containing carcinogenic formaldehyde, etc.), thus increasing technical obstacles for the practical application and promotion of vehicle methanol fuel and vehicle methanol gasoline

Abstract

The invention relates to a methanol denaturation additive, which is prepared from the following components in part by weight: 50 to 90 parts of isopropanol, 3 to 20 parts of cyclohexane, 5 to 10 parts of No.1 aviation kerosene, 0.1 to 0.9 part of zinc peroxide, 1 to 10 parts of dimethyl carbonate, 4 to 15 parts of isooctyl nitrate, 3 to 10 parts of fatty acid methyl ester, and 0.1 to 0.9 part of 2,6-di-tert-butyl paracresol. The methanol denaturation additive has the advantages that: the zinc peroxide has extremely strong activity after pyrolysis in an engine, can clear organic peroxides generated when the methanol is in anoxic combustion, discharges trace oxygen during pyrolysis, and generates 'micro blasting effect'; and the trace 'oxygen bomb' is enough to make the formaldehyde substance generated by anoxic combustion of the methanol generate 'blasting' combustion so as to promote full combustion of alcohol ether fuels such as methanol and the like.

Description

technical field [0001] The invention relates to a chemical additive, in particular to an additive used for denaturation treatment of methanol fuel for vehicles and methanol gasoline. Background technique [0002] With the scarcity of oil resources and the soaring price of international crude oil, there are more and more technologies at home and abroad to develop oil substitute products using methanol as raw material. However, the vast majority of methanol and fossil gasoline are simply blended or only part of the co-solvent is added, and the selected methanol raw material is not denatured, thus exposing a series of problems when methanol and fossil gasoline are deployed and used (such as Low combustion efficiency, high fuel consumption, power drop, low-temperature cold start, stratification, emulsification, and carcinogenic formaldehyde in exhaust emissions), thus increasing technical obstacles for the practical application and promotion of vehicle methanol fuel and vehicle ...
