Production technical formula of high-methanol-proportion gasoline

Abstract

The invention relates to a production technical formula of high-methanol-proportion gasoline, which is the key feature of the technique and determines the addition amount of the methanol raw material in the methanol gasoline and the quality of the oil product. The modification process of the methanol raw material is implemented by adding proper amounts of appropriate mutually-soluble reaction raw materials-n-butanol, tert-butyl alcohol, liquid paraffin, petrobenzene and n-octane. The addition of the raw materials can greatly enhance the blending amount of the methanol to higher than 50%, can effectively solve the problem of mutual solubility of the methanol gasoline and the corrosivity of the methanol gasoline to the power machine, improves the anti-swelling property of rubber, enhances the heating value and octane number of the methanol gasoline, and solves the problems of low heat value and difficulty in cold starting. The high-methanol-proportion gasoline is mainly prepared from 50-85% of methanol, 15-50% of petrochemical gasoline, 0.1-0.3% of n-butanol, 0.1-0.5% of isopropanol, 5-10% of light oil, 0.5-1% of oleic acid, 0.2-1% of liquid paraffin, 1-3% of petrobenzene and 0.0005-0.001% of n-octane.

Description

technical field [0001] The present invention relates to a kind of technical formula and its production process that make full use of my country's cheap and renewable chemical by-products-methanol, petrochemical gasoline and appropriate additives, and mix and deploy them into methanol gasoline at a ratio of 50-85%. Petrochemical gasoline has a small blending ratio, poor mutual solubility, easy delamination, poor dynamic performance, and easy swelling and corrosion of oil pipes and gaskets. The purpose is to reduce the cost of petrochemical gasoline to a greater extent from the technical level and improve The utilization efficiency of methanol gasoline can further reduce the problem of my country's dependence on foreign oil energy. Background technique [0002] At present, research on blending alcohol-based gasoline with methanol and petrochemical gasoline is in the ascendant in China, because methanol is a renewable biomass energy and a by-product of petroleum and coal chemical...
