Problems solved by technology

But the aviation kerosene used is expensive, and the antifreeze effect is not ideal
[0004] At present, the problems of diesel pour point depressants with similar functions are still single function and large amount of addition, and the products are supplied to refineries as pour point depressant additives, and consumers cannot directly use them.

Abstract

The invention relates to the technical field of petrochemical engineering, and particularly relates to a smoke-eliminating antifreezing agent for diesel oil. The antifreezing agent is prepared from the following raw materials in parts by weight: 20-35 parts of polymethacrylate, 10-20 parts of sodium gluconate, 8-17 parts of Fe(C5H5)2, 10-20 parts of polyethylene glycol, 20-30 parts of glycerol, 1-5 parts of polytetrafluoroethylene, and 10-18 parts of alkyl glycoside. The smoke-eliminating antifreezing agent for diesel oil disclosed by the invention can keep continuously supplemental firing, and can significantly reduce the condensation point and cold filter plugging point of diesel oil, prevent the diesel oil from being frozen at low temperature, clean parts, improve the effect of smoke elimination, and reduce the emission of exhaust gas.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to a diesel smoke extinguishing and antifreezing agent. Background technique [0002] Diesel is widely used as engine fuel for trucks, buses, tractors, locomotives, ships and various agricultural, construction, mining, and military machinery and equipment due to its low economic cost and strong power. However, due to the quality characteristics of diesel and the high-pressure injection combustion method, the emission of black smoke from diesel engines is very serious. How to solve the problem of serious pollution from diesel engines has also become a hot topic around the world. Due to the quality characteristics of diesel oil, its paraffin molecules are prone to form eutectic crystals at low temperatures in winter and block the oil circuit. This phenomenon has always troubled the majority of diesel consumers since diesel. The common solution is to use dangerous open ...
