The emission reduction diesel antifreezing agent is prepared from, by weight, 20-35 parts of polymethacrylate, 10-20 parts of polyethylene glycol, 10-18 parts of alkyl glycoside, 5-12 parts of dimethyl ether, 8-18 parts of antioxidant and 7-17 parts of octane value promoter. The emission reduction diesel antifreezing agent can be kept in continuous intensified combustion, condensation point and cold filter plugging point of diesel can be lowered remarkably, the diesel is prevented from being frozen at low temperature, parts are cleaned, smoke abatement effect is improved, and exhaust gas emission is reduced.
Description
Technical field
The present invention relates to technical field of petrochemical industry, particularly one reduces discharging diesel oil frostproofer.
Background technology
Diesel oil because its Financial cost is cheap, dynamic property strong, and is widely used in the motor spirit of cargo truck, motorbus, tractor, locomotive, boats and ships and various agricultural, building, mine, military mechanized equipment.But because of mass property own and the high pressure spraying combustion system of diesel oil, the discharge over-emitting black exhaust phenomenon of diesel engine is very serious, how to solve diesel emission this problem seriously polluted and also becomes worldwide heat subject.Diesel oil is the Crystallization Plugging oil circuit because easily forming eutectic under its paraffin molecule of mass property in the winter time low temperature again, has annoying vast diesel oil human consumer since this phenomenon has diesel oil by oneself all the time.Common solution adopts dangerous naked light to bake car measure to alleviate the oil circuit caused due to wax crystal to freeze, do both dangerous like this, ineffective again, even can cause the safety of fire threat to life and property, for dilly, once freeze, then only have and to thaw with hot water and effect is undesirable, and length consuming time, waste energy.
And the problem existing for diesel pour inhibitor of approximation function is still function singleness at present, addition is large, and product supply refinery is used as pour point depression additive, and human consumer can not directly use.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind of reduces discharging diesel oil frostproofer, and it can keep lasting overheavy firing, significantly can reduce condensation point and the cold filter clogging temperature of diesel oil, and prevent diesel from freezing under low temperature, clean parts, improve smoke effect, reduce exhaust emissions.
For achieving the above object, the present invention adopts following technical scheme:
A kind of reduction of discharging diesel oil frostproofer, be made up of the raw material of following weight part:
Antioxidant of the present invention is the mixture of the p-di-iso-octyldiphenylamine of 10 ~ 20 weight part and the tertiary Ding-4-methylphenol of 18 ~ 28 weight parts 2,6-bis-.Add antioxidant, the usage period of diesel oil can be extended, be convenient to preserve.
Octane rating promoter of the present invention is the mixture of 10 ~ 20 weight part tert.-butyl acetates, 12 ~ 22 weight part crotonamides and 15 ~ 25 weight part methyl cyclopentadienes.Octane rating promoter is mixed by several material, improves fuel octane number amplitude, makes burning more stable, on oxygen sensor without impact, can reduce oxynitride and carbon monoxide emission, comparatively clean environment firendly.
Both containing polarity oxy radical in polymethacrylate molecule of the present invention, again containing side chain non-polar group, there is adsorption, also there is pendant alkyl group and wax molecule cocrystallization at a certain temperature, and make whole molecule and interconnection of paraffin crystalline particles present " branch " shape, wax crystalline substance is scattered on " branch " not easily grow up, thus plays the eutectic effect reducing condensation point effect; Meanwhile can play stop wax crystalline substance to be grown up due to the polar functionalities in its molecule, the condensation point of diesel oil and cold filter clogging temperature are reduced.
The polyoxyethylene glycol that the present invention uses is nontoxic, non-stimulated, has good dispersiveness, can reduce cold filter point of diesel oil and condensation point.Owing to having colloid in diesel oil, easily in engine, form carbon distribution, affect automobile power, increase oil consumption, the polyoxyethylene glycol added in the present invention's formula, effectively can reduce gum level, add that it is as the inherently good cleaning of alcohols and thinner, therefore can prevent carbon deposit from generating, increase ignition intensity, increase the tightness into and out of valve.
Alkyl glycoside is synthesized by renewable resources natural fat alcohol and glucose, it is the more comprehensive new non-ionic surfactants of a kind of performance, it has the characteristic of conventional nonionic and anion surfactant concurrently, having high surface, good ecological security and intermiscibility, is internationally recognized first-selection " green " functional surfactant.The long alkyl chain of alkyl glycoside can with the mutual effect of wax crystalline phase, make the two ends of wax crystalline substance have polarity, thus crystal better disperses, effectively can hinder again the growth of wax crystalline substance, the lubricity between crystal can also be added, thus the probability connected between crystal is reduced, effectively reduce condensation point.
Preferably, reduction of discharging diesel oil frostproofer of the present invention, be made up of the raw material of following weight part:
There is not carbon atom in dme directly to connect, therefore soot can not be produced in combustion processes, reduce in Diesel Emissions tail gas and discharge without visible particle thing, oxygen level due to dme is 34.8%, be easy to perfect combustion, be conducive to reducing the pollutant load in exhaust emissions, improve the combustionproperty of automobile fuel, improve the cetane value of fuel, improve mutual solubility and the susceptibility of diesel oil and this frostproofer.
Beneficial effect of the present invention is:
Reduction of discharging diesel oil frostproofer of the present invention, it can keep lasting overheavy firing, significantly can reduce condensation point and the cold filter clogging temperature of diesel oil, prevents diesel from freezing under low temperature, and clean parts, improve smoke effect, reduce exhaust emissions.Test-results shows, after using reduction of discharging diesel oil frostproofer of the present invention, the condensation point of diesel oil is down to-40 ~-30, the more existing frostproofer of cold filter clogging temperature reduces by 10 ~ 15 DEG C, reduces by 60 ~ 75% soot emissions, clean environment firendly, storage time can reach a year and a half more than, stablizes not stratified.
