Abstract

The invention provides a methanol gasoline denaturant and a preparation method thereof. The methanol gasoline denaturant is composed of methanol gasoline phase separation inhibitor, methanol gasoline corrosion inhibitor, methanol gasoline vapour pressure regulator, formic acid, formaldehyde and methanol complete combustion improver, and a coordination mechanism is formed. The methanol gasoline phase separation inhibitor accounts for 30-50%, the methanol gasoline vapour pressure regulator accounts for 2-10%, the complete combustion improver accounts for 30-67%, and the methanol gasoline corrosion inhibitor accounts for 1-10%, and the four components are synthesized under specific production conditions. The amount of the methanol gasoline denaturant added to methanol gasoline is 0.5-2% (mass ratio), common gasoline No. 90 can be used for producing clean methanol gasoline No. 93 and clean methanol gasoline No. 97, all the performances of the methanol gasoline are improved, and long term storage and normal use of the methanol gasoline are realized.

Description

technical field [0001] The invention belongs to the technical field of clean fuel production, and in particular relates to the preparation of a methanol-gasoline denaturant for vehicles, which is a key production technology of methanol-gasoline. Background technique [0002] The development of human society is facing the dual pressure of resources and the environment. In order to promote the sustainable development of social economy, the development of clean alternative vehicle fuels has attracted the attention of all countries in the world. At present, alternative fuels mainly include: alcohols such as methanol, ethanol, 1.4-butanediol, esters such as fatty acid methyl ester, fatty acid ethyl ester, ethers such as dimethyl ether, etc., as well as hydrogen and natural gas. [0003] my country's development of alternative fuels has its own national conditions. It is impossible for my country's grain ethanol to grow larger, and non-grain crops need land resources; fuel cells a...
