Problems solved by technology

[0002] At present, the technology popularized and used in China generally only physically blends 15% to 25% methanol with finished gasoline. Because methanol itself has a large latent heat of vaporization, its chemical calorific value is much lower than that of gasoline, and its combustion efficiency is low.

Abstract

This invention relates to a method for preparing leadless composite gasoline added with methanol and ethers. The leadless composite gasoline is composed of: methanol 50-80 parts, gasoline product 10-30 parts, naphtha 20-30 parts, isobutanol 0.5-14 parts, methyl-tert-butyl ether 1-8 parts, petroleum benzene 0.1-10 parts, petroleum ether 0.3-10 parts, additives 0.1-3 parts and assistant liquid 0.2-0.5 part. The additives are mixed from zinc peroxide, dimethyl carbonate, and vat yellow, cyclohexylamine and isooctyl nitrate. The assistant liquid is prepared from n-butanol, petroleum benzene and cyclohexylamine. The method comprises: (1) preparing the additives; (2) preparing the mother gasoline; (3) preparing modified methanol; (4) preparing modified naphtha; (5) preparing the synthetic liquid; (6) mixing with the assistant liquid to obtain leadless composite gasoline. The obtained leadless composite gasoline has high methanol content.

Description

technical field [0001] The invention relates to a composite catalytic lead-free alcohol-ether gasoline blended with a large proportion of methanol and a preparation method thereof. Background technique [0002] At present, the technology popularized and used in China generally only physically blends 15% to 25% methanol with finished gasoline. Because methanol itself has a large latent heat of vaporization, its chemical calorific value is much lower than that of gasoline, and its combustion efficiency is low. Therefore, increasing the application ratio of methanol, reducing the cost of composite catalytic lead-free alcohol ether gasoline, and simultaneously improving the combustion efficiency of composite catalytic lead-free alcohol ether gasoline are problems to be solved urgently. Contents of the invention [0003] One of the purposes of the present invention is to address the above problems, to provide a composite catalytic unleaded alcohol ether gasoline that adopts a l...
