Abstract

The invention discloses a modified methanol synthesized lead-free gasoline with high cleanness. The modified methanol synthesized lead-free gasoline with high cleanness is prepared by the following components by parts by weight: 30-60 parts of methanol, 30-40 parts of No. 60-No.70 crude gasoline, 0.8-1.5 parts of n-butanol, 1.0-10 parts of coking light oil, 0.3-0.5 part of dimethyl sulfoxide, 0.3-0.5 part of coconut oil polyoxyethylene ether-(20), 0.1-0.3 part of fatty alcohol polyoxyethylene ether-(40), 0.4-0.6 part of dioctyl phthalate, 0.4-0.6 part of dibutyl phthalate, 3-5 parts of dimethyl ether, 1-3 parts of trimethyl carbonate and 0-5 parts of No.6 solvent oil. The modified methanol synthesized lead-free gasoline with high cleanness has small polarity and weak corrosion, exhaust gasdoes not contain formaldehyde, and no atmospheric pollution is produced.

Description

Technical field [0001] The invention relates to a liquid fuel, specifically a high-clean unleaded gasoline synthesized from modified methanol Background technique [0002] At present, methanol gasoline prepared by cold blending at room temperature and pressure has the defects of high polarity and strong corrosiveness in the product oil, and the exhaust tail gas contains a small amount of toxic formaldehyde to pollute the atmosphere. Summary of the invention [0003] The purpose of the present invention is to provide a modified methanol synthesis high-clean unleaded gasoline with low polarity, weak corrosiveness, no formaldehyde in the exhaust gas, and no air pollution, so as to meet the needs of use. [0004] The present invention is realized as follows: [0005] The modified methanol synthesized high-clean unleaded gasoline of the present invention is made of the following components by weight: [0006] 30-60 parts of methanol, 60 # -70 # 30-40 parts crude gasoline, [0007] 0.8-1.5 p...
