Abstract

The invention belongs to the technical field of fuel oil additives, and specifically relates to a clean fuel oil antiknock additive. The antiknock additive is characterized by being composed of the following raw materials in parts by weight: 35 to 45 parts of low-carbon alcohol, 10 to 20 parts of bis-succinamide, 7 to 9 parts of hexahydrobenzoic acid, 1 to 3 parts of 2,6-di-tert-butyl mixed phenol, 1 to 2 parts of trimethyl phosphate, 5 to 7 parts of benzotriazole derivatives, 2 to 4 parts of sodium hydroxide, 9 to 11 parts of zinc oleate, and 1 to 3 parts of tert-butyl benzene. The provided antiknock additive can effectively improve the antiknock performance of fuel oil, is harmless and non-toxic, is capable of prominently improving the octane value of gasoline, can improve the octane value by 8 to 20 units, and does not have any side effect on the engine or storage tank. The using conditions of the antiknock additive are the same as those of the gasoline. The antiknock additive has the advantages of simple technology, low cost, and user-friendliness.

Description

technical field [0001] The invention belongs to the technical field of fuel additives, in particular to a clean fuel antiknock agent. Background technique [0002] If gasoline is burned under the condition of engine knock, the engine power will be reduced, and extremely high pressure shock fluid will be generated, which will cause additional wear of important parts such as engine, piston, piston pin, bearing and so on. [0003] For the knocking problem when gasoline burns in the cylinder, it is proposed to increase the octane number in gasoline to solve it. At present, the main approach is to improve the refining process and process or to use additives. But the octane number of the prior art depends on the factory state of the refinery, and its anti-knock performance is difficult to improve due to cost constraints. The present invention can be used in oil refineries, effectively improves the anti-knock performance, and further reduces the cost. Olefin content. Contents o...
