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 suppressing and antifreezing agent. Background technique [0002] Due to its low economic cost and strong power, diesel is widely used as engine fuel for trucks, buses, tractors, locomotives, ships, and various agricultural, construction, mining, and military machinery and equipment. However, due to the quality characteristics of diesel oil 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 emission pollution from diesel engines has become a hot topic worldwide. Due to the quality characteristics of diesel oil, its paraffin molecules tend to form eutectic crystals at low temperature in winter and crystallize to block the oil passage. This phenomenon has always troubled the majority of diesel oil consumers since the diesel oil was produced. A common s...
