Vehicular series methanol gasoline and preparing method thereof

Abstract

The present invention discloses a series of methanol gasoline for automobiles and a preparation method thereof. The methanol gasoline comprises (by weight parts) catalytic cracking gasoline 50 to 80, denatured methanol 3 to 40, and environment-protection non-benzene 120 solvent oil 5 to 20, wherein the denatured methanol comprises (by weight parts) oligomeric active polyisobutylene amine 70, ethyl hexa-nitroaniline 1, water-free fusel oil 20, ethanol 9, and methanol 900. The preparation method of the methanol gasoline comprises the following steps of: (A) adding the water-free fusel oil into a mixing tank according to the ratio, sequentially adding the ethanol, the oligomeric active polyisobutylene amine, the ethyl hexa-nitroaniline and the methanol, and mixing uniformly to obtain the denatured methanol; and (B) adding the denatured methanol into the mixing tank, respectively adding the environment-protection non-benzene 120 solvent oil and the catalytic cracking gasoline, and mixing uniformly. The methanol gasoline is suitable for automobile in summer to prevent the occurrence of air lock, and has the advantages of simple preparation method and convenient popularization.

Description

technical field [0001] The invention relates to a series of methanol gasoline for vehicles and a preparation method thereof. Background technique [0002] The proportion of catalytic cracked gasoline in gasoline is as high as 78%, and the saturated vapor pressure of this oil is high. The methanol gasoline prepared with it as the main raw material, such as: MH3, MH5 until MH50 has the following deficiencies in the application of ordinary fuel engines: 1. methanol and low boiling point components in catalytic cracking gasoline (C 4 Alkenes) azeotrope effect will cause higher saturation vapor pressure. As a result, the use of automobile engines in summer will produce air locks, which will block the flow of gasoline and cause flameouts. At the same time, it brings volatile pollution and traffic safety hazards. 2. Due to the large latent heat of evaporation of methanol and the low calorific value, the starting performance of the engine is not good. Contents of the invention ...

AI Technical Summary

Problems solved by technology

The methanol gasoline prepared with it as the main raw material, such as: MH3, MH5 until MH50 has the following deficiencies in the application of ordinary fuel engines: 1. methanol and low boiling point components in catalytic cracking gasoline (C 4 Alkenes) azeotropic effect will cause higher saturated vapor pressure

As a result, when using the car engine in summer, air lock will occur, blocking the flow of gasoline and causing flameout

At the same time, it brings volatile pollution and hidden dangers to driving safety

2. Due to the large latent heat of evaporation of methanol and the low calorific value, the engine startability is not good
