Abstract

The invention provides a preparation method for methanol gasoline with good stability, and belongs to the technical field of synthetic fuels. The preparation method comprises the following steps: steps one, putting heavy benzol, alkyl naphthalene, amyl nitrate, sodium biphosphate, ethylene-vinyl acetate copolymer, light diesel oil, tebutate peroxide, 70# gasoline, a dispersing agent, and a metal deactivator into a reactor and stirring to obtain a mixture; adding methanol into the mixture, cooling down, stirring continuously, and standing to obtain the methanol gasoline. The methanol gasoline provide by the invention has good burning performance, and is not changed in performance and has no sediments after being placed for a long time.

Description

[0001] technical field [0002] The invention provides a method for preparing methanol gasoline and belongs to the technical field of synthetic fuels. [0003] Background technique [0004] my country's domestic recoverable coal reserves are about 700 billion tons of standard coal, which can be used for about 200 years based on the national annual total energy demand of 3 to 4 billion tons of standard coal. According to the information from the Ministry of Land and Resources, in 2007, my country's remaining recoverable oil reserves were about 2.043 billion tons; according to the current 123-170 million tons / year production, it can be recovered for up to 26 years. Domestic oil will face depletion around 2030. In 2009, China's net oil imports, including crude oil, refined oil, liquefied petroleum gas and other petroleum products, reached 218 million tons, a year-on-year increase of 8.8%; crude oil imports exceeded 200 million tons for the first time, reaching 203 million...
