Abstract

The invention relates to a polyether oxygen-containing cleaning synergist composition for clean gasoline. The polyether oxygen-containing cleaning synergist composition is prepared from the followingfour raw materials in parts by weight: 400 to 1000 parts of diisobutyl oxalate, 5 to 15 parts of vegetable oil acid, 5 to 15 parts of HF-B100 polyether amine, 400 to 1000 parts of polyoxymethylene dimethyl ether and the like. A preparation method includes: feeding the raw materials into an oil mixing tank to be uniformly stirred, filtering the mixture with a 400-mesh (30 mu m) filter screen, and carrying out standing treatment for 24 hours to obtain the polyether oxygen-containing cleaning synergist, which is clear and colorless and has a beer-like color, for gasoline. The invention further relates to a composition with a better effect obtained by modifying the raw materials through microorganisms.

Description

technical field [0001] The invention relates to the field of clean energy, in particular to a polyether oxygen-containing detergent synergist composition for gasoline. Background technique [0002] Gasoline is obtained by refining straight-run gasoline components, catalytically cracked gasoline components, catalytic reformed gasoline components and other gasoline components, which are refined and blended with high-octane components, and are mainly used for automobile ignition. fuel for internal combustion engines. At present, in the field of gasoline, there are many enhanced fuel-saving agents with different properties and effects. Fuel-saving agent is an additive compounded with various chemical components. Different fuel-saving agents have different fuel-saving effects due to different ingredients added. At the same time, they also have the functions of removing carbon deposits and cleaning oil passages, thereby saving Fuel, enhance power, protect the efficiency of the e...
