Abstract
The present invention relates to an improvement for a combustion-supporting additive for gasoline and diesel oil, which is characterized in that isooctanoic acid metal salts are utilized to replace metal naphthenate and the ratio of all components is adjusted. Compared with the naphthenic acid series, the combustion-supporting additive has the advantages of better fuel-saving effect, no stratification, no deposition and good storage stability, and at the same time, the combustion-supporting additive has good pour point depression effect and lubricating action. The combustion-supporting additive can be used as a '0'-reducing agent, which changes the deficiency that the NO. 0 diesel oil can not be used in cold areas.
Description
The present invention relates to a kind of improved petrol and diesel oil perfect combustion catalyzer.
For example add a small amount of additive in the diesel oil at fuel oil, by changing fuel characteristics and catalytic combustion-supporting, improve burning thereby reach, carbon deposit and black smoke discharging in minimizing and removing boiler oil nozzle and the engine, save fuel oil, people are constantly seeking various high efficiency fuel ignition dopes for this reason.A kind ofly use more combustion promoter for diesel oil for adopting the composite composition of metallic naphthenate, reported the diesel oil perfect combustion catalyzer of the composite composition of magnesium naphthenate of iron naphthenate, the 2-25% of cobalt naphthenate, the 5-40% of manganese naphthenate, the 2-25% of calcium naphthenate with 15-50%, 15-50% as Chinese patent 94100545.This by the composite ignition dope of forming of metallic naphthenate, its main drawback is that the pour point depression effect is undesirable, thereby not ideal enough in the extremely frigid zones result of use; Secondly the ignition dope stability of the composite composition of metallic naphthenate is good inadequately, adds the back along with time lengthening is prone to muddiness, precipitation, layering, not only not anti-storage, but also meeting plug nozzle; And naphthenic acid because of the low ability of acid number in conjunction with catalytic metal ion a little less than, the catalytic combustion-supporting effect is not really desirable; The naphthenic acid flash-point is lower, and production, transportation, storing stability are poor.Chinese patent 91104967 is disclosed to add a small amount of 2-ethylhexoate again in metallic naphthenate, as adopt the naphthenate of 40-99%, the 2-ethylhexoate of 1-45%, the surfactant compound of 0-25% to form perfect combustion catalyzer, its major ingredient is still metallic naphthenate, just according to different purposes arrange in pairs or groups a spot of isooctoate of rare earth metal, isocaprylic acid nickel or zirconium iso-octoate, thereby use the weakness of naphthenate effectively not taken on a new look.
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of pour point depression, catalytic combustion-supporting effect and keeping quality better, the petrol and diesel oil perfect combustion catalyzer that use properties is more excellent, security is good.
The object of the invention realizes that main the improvement is to adopt the isocaprylic acid metal-salt to replace metallic naphthenate, and adjusts each raw material proportion of composing.Specifically, gasoline and diesel combustion-supporting agent of the present invention is characterized in that comprising the calcium iso-octoate of 40-55%, the manganese iso-octoate of 20-35%, the cobalt iso-octoate of 5-10%, the isooctoate of rare earth metal of 5-10%, the isocaprylic acid iron composition of 10-15%.Isooctoate of rare earth metal of the present invention is preferably for adopting the group of the lanthanides rare earth chloride.Described isocaprylic acid iron preferably uses the ferric iron of isocaprylic acid.
For making the catalytic combustion-supporting better effects if, reduce corrosion of metal damage also is added with the isocaprylic acid copper of 1-5% in the ignition dope of the present invention, isocaprylic acid copper preferably uses the cupric of isocaprylic acid.Also can be added with the cetane number booster of 0.2-1% among the present invention,, reduce anti-knocking property, make the machine operation more steady to improve the label quality of diesel oil.
The preparation of ignition dope of the present invention only needs above each component is mixed in proportion, gets final product through stirring.
Further specify the present invention below in conjunction with several embodiment.
Embodiment 1: with commercially available calcium iso-octoate 35Kg, manganese iso-octoate 35Kg, cobalt iso-octoate 5Kg, group of the lanthanides isocaprylic acid rare earth chloride 10Kg, isocaprylic acid ferric iron 15Kg, mixing was stirred through 1 hour, add in 0 diesel oil with 0.2% addition, in the still normally oil spout of subzero 10-15 degree nozzle, the boiler of power plant average rate of economizing gasoline that burns is 16-20%.
Embodiment 2: with commercially available calcium iso-octoate 50Kg, manganese iso-octoate 20Kg, cobalt iso-octoate 10Kg, group of the lanthanides isocaprylic acid rare earth chloride 5Kg, isocaprylic acid ferric iron 10Kg, isocaprylic acid cupric 5Kg, mixing was stirred through 1 hour, add in 0 diesel oil with 0.2% addition,, normal ignition running rapid at subzero 10-15 degree diesel engine starting, the generating set rate of economizing gasoline is 15-18%.
Embodiment 3: add the cetane number booster of 0.2-1% in above-mentioned prescription, be used for low grade diesel oil and improve the label quality.
Ignition dope of the present invention, owing to adopt the isocaprylic acid metal-salt and adjust the each component ratio, because isocaprylic acid acid number height, can engage metal ion in the more fuel oil than naphthenic acid, thereby have than naphthenic acid ignition dope better catalytic combustion-supporting function and polymerization are arranged, combustion-supporting effect is better, make an addition in the diesel oil through the automobile preventing test, average rate of economizing gasoline is 16-18%, than the high 5-8% of naphthenate ignition dope, the generating set rate of economizing gasoline is 15-20%, exceeds naphthenic acid ignition dope 3-6%.Simultaneously because the low zero pour of isocaprylic acid, the pour point depression effect is better than naphthenic acid greatly, can be used as to fall " 0 " agent use, and No. 0 diesel oil is reached-10 to-No. 20, No. 0 diesel oil can replace-No. 10 ,-No. 20 diesel oil normally to use at subzero 15 ℃, not only combustion-supporting but also pour point depression.In addition because isocaprylic acid is oil soluble, and purity height, additive be good dispersity in oil not only, but add the back not stratified, do not precipitate long storage; And oil film can improve the engine extreme boundary lubrication attached to forming layer protecting film on the metallic walls, reduces wear, and engine cylinder is had the better protecting effect, therefore has catalyticcombustion and lubricated dual-use function again.The better combustion-supporting and antisepsis and sterilization effect of hormany catalyt of the interpolation of isocaprylic acid copper reduces corrosion of metal is damaged.Ignition dope of the present invention not only is used for diesel oil, also can be used for gasoline, has similar effect.
