Abstract

The invention discloses a nonmetallic gasoline additive and a method for preparing the same. The nonmetallic gasoline additive comprises, by weight, 0.5-12% of polyether, 0.5-12% of polyether polyol,0.5-10% of poly-alcohol, 0.1-15% of catalysts, 0.1-15% of stabilizers, 1-16% of soluble silicic acid and 55.9-92% of polyol. The method includes adding the polyether, the polyether polyol, the poly-alcohol and the catalysts into the polyol; carrying out stirring reaction to obtain transparent oily liquid; adding the soluble silicic acid into the liquid; carrying out stirring reaction at the temperature of 80-110 DEG C until solution turns clear; filtering the clear solution to obtain the nonmetallic gasoline additive. The nonmetallic gasoline additive and the method have the advantages that more than 18% of gasoline can be saved by the aid of the nonmetallic gasoline additive under identical conditions, emission of hydrocarbon HC, carbon monoxide CO, PM (particulate matters) and nitrogen oxide NOx can be reduced to a great extent, the smoke intensity can be lowered to a great extent, and effects of inhibiting carbon deposit generation and eliminating carbon deposits can be realized; the nonmetallic gasoline additive is stable in property, can be safely stored and transported and is free of damage to gasoline cylinders and engines, the nonmetallic gasoline additive and gasoline arecompletely mutually soluble, precipitation and layering can be prevented.

Description

technical field [0001] The invention belongs to the field of gasoline and fuel, in particular to a non-metallic gasoline additive and a preparation method thereof. [0002] technical background [0003] Automobile fuel Gasoline is an important transportation fuel, its output accounts for about 20% of the crude oil processing volume, and its demand is increasing rapidly year by year due to the increase in car ownership, and its main components are chains of C5-C11 Alkanes, aromatics, cycloalkanes, alkenes, and a small amount of compounds containing heteroatoms such as nitrogen, sulfur, and oxygen, etc. [0004] In recent decades, with economic development, people's living standards have gradually improved, the demand for automobiles has increased sharply, and the rapid development of the global, especially domestic, automobile industry has led to a rapid increase in fuel consumption and increased air pollution over cities and beside expressways. Countries all over the world h...
