Modified methanol and preparation method thereof

Abstract

The invention relates to modified methanol. The modified methanol is prepared from the following components in part by weight: 80 to 90 parts of methanol and 3.16 to 15.38 parts of methanol modified additive; and the methanol modified additive 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 aviation kerosene No.1, 0.1 to 0.9 part of zinc peroxide, 1 to 10 parts of dimetyl 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-4-methylpenol. The invention has the advantages that: the cyclohexane and the 2,6-di-tert-butyl-4-methylpenol are compounded, so that the modified methanol has high corrosion resistance and swelling resistance; the isopropanol and the fatty acid methyl ester are compounded, so that the water resistance of vehicle methanol gasoline is improved by more than two times; surfactant fatty acid methyl ester, the fatty acid methyl ester and the isopropanol are compounded, so that the added methanol and fossil gasoline can be mutually dissolved according to any proportion, and the problems of low-temperature layering and emulsification layering of the methanol gasoline are solved thoroughly; and the aviation kerosene No.1 is added so as to solve the problem of low-temperature cold boot of the methanol gasoline.

Description

technical field [0001] The invention relates to the field of chemical fuels, in particular to denatured methanol fuel for vehicles and a production method thereof. Background technique [0002] With the reduction of petroleum resources and the improvement of coal chemical technology level, it has become a top priority to promote the use of methanol fuel for vehicles and methanol gasoline with methanol as raw material. For this reason, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the National Standardization Management Committee promulgated the national standard for methanol fuel for vehicles (GB / T 23510-2009) on April 8, 2009. Methanol needs to be used for vehicles or blended with fossil gasoline. Only denaturation treatment can overcome the problems of low combustion efficiency, cold start at low temperature, high fuel consumption, power drop, stratification, emulsification, and carcinogenic formaldehyde ...
