Gasoline additive and preparation method therefor

Abstract

The invention discloses a gasoline additive and a preparation method therefor. The gasoline additive is prepared from the following raw materials: methyl acetate, ethanol, 3-lauryl thiopropionate, polyacrylamide, hydrogenated castor oil, polyisobutene ethyl carbamate and a catalyst. The raw materials are good in intermiscibility with gasoline, so that the physical and chemical performance indexes of an oil product are comprehensively enhanced, the octane number of gasoline can be remarkably improved, the gasoline additive has an excellent anti-explosive effect, has a good cleaning effect on gasoline, and enables gasoline to fully combust, and therefore, the heat efficiency of fuel oil and the output per liter of an engine is improved.

Description

technical field [0001] The invention belongs to the field of fuel additives, in particular to a gasoline additive and a preparation method thereof Background technique [0002] While automobiles bring comfort and convenience to our lives, they also cause certain pollution to the natural environment. As we all know, during the combustion process of automobile fuel, some harmful automobile exhaust will be emitted through the exhaust pipe of the automobile. These Exhaust gas includes CO, incompletely burned hydrocarbons HC, NO x and particulate matter PM etc. These substances will cause harm to human health and the environment. In order to improve the quality of fuel and improve its performance, many fuel additives have appeared on the market for gasoline. Combustion-supporting effect, some provide oxygen-enriched components to fully burn fuel, etc., all perform well in a single aspect, but the overall performance is average. [0003] For example, the application number is a...

These substances will cause harm to human health and the environment. In order to improve the quality of fuel and improve its performance, many fuel additives have appeared on the market for gasoline. Combustion-supporting effect, some provide oxygen-enriched components to fully burn fuel, etc., all perform well in a single aspect, but the overall performance is average

[0003] For example, the application number is a fuel additive of 200810072498.7, which is composed of dialkyl carbonate with general formula R1OCOOR2, biscyclopentadienyl iron, benzotriazole, fatty alcohol and ethylene oxide condensate, Alkylphenol and ethylene oxide condensate, although it considers the oxygen-rich components and combustion-supporting effect, it is not good in oxidation resistance and gasoline cleansing and dispersibility. In addition, dicyclopentadienyl iron, and manganese agent, Like lead agent, because the combustion emissions will be deposited on the surface of the combustion chamber, intake valve and spark plug, it will affect the normal operation of the engine and damage the exhaust after-treatment system over time. Now the new "Automotive Gasoline" standard also includes It is stipulated that lead and iron additives shall not be artificially added
