Abstract
The present invention relates to a smoke-abating combustion improver for diesel oil and heavy oil, which contains 1 to 10 wt% of oil-soluble nano-iron, 5 to 25 wt% of cobalt naphthenate, 10 to 30 wt% of barium naphthenate, 5 to 10 wt% of polyisobutene diimide, 1 to 5 wt% of long-chain fatty acid and a solvent as the rest. A preparation method of the smoke-abating combustion improver comprises the steps: at normal temperature, the cobalt naphthenate, the barium naphthenate, the oil-soluble nano-iron and the long-chain fatty acid are orderly added to the solvent and are uniformly stirred; then, the polyisobutene diimide is added to the solvent and is uniformly stirred to prepare the smoke-abating combustion improver. The smoke-abating combustion improver comprises the nano-iron and the cobalt naphthenate as active components for catalyzing and supporting combustion, so that fuels generate a large amount of free radicals of hydrocarbon during combustion, the oxidation speed is accelerated, and the combustion is more complete, and as a result, the combustion efficiency is enhanced, the fuel is considerably saved by 5 to 20%, and the discharge smoke can be reduced by 30 to 60%. The preparation method of the present invention has the advantages of simplicity, lower overall cost, no need of changing an oil supply system and very convenient and easy popularization.
Description
Technical field
The present invention relates to fuel oil additive, be specifically related to a kind of smoke-eliminating combustion-aid additives that is used for diesel oil, heavy oil.
Technical background
According to U.S.'s the Center for Strategic and International Studies report, in 20 years from now on, the world energy sources demand will increase by 50%.At present, the energy of developed country's consumption is more than developing country.The energy of state consumption will be above developed country in certain stage development from now on.Along with socioeconomic fast development, transport facility and engineering machinery are increasing, the demand of fuel oil are also increased sharply, because fuel oil machinery exhaust gas discharged also is on the rise to the pollution of atmospheric environment.How to make full use of limited mineral fuel, improve the thermo-efficiency of oil inflame, reduce fuel oil consumption, reduce the discharging of combustion exhaust, alleviate pollution, become important technology that various countries, the world today face from problem to atmospheric environment.In recent years, for developing new fuel oil additive, people did many effort.The fuel oil additive that provides as patented technologies such as US 5693106, US 5087267, US 4891049, CN 1113087, CN 85109511, though played the effect that improves the oil inflame performance to a certain extent, had that the fuel oil additive function is few, the single deficiency of effect.Only having considered of having solves combustion-supporting problem, and do not consider to reduce the problem of oil consumption, also considers less to the content of harmful that reduces in the fuel oil machinery discharging waste gas; Have plenty of the precious metal salt of utilization and do the catalytic activity agent, cost is higher; Have plenty of and utilize multiple water-soluble metal salt as the catalytic activity thing, oil soluble is bad, dispersiveness and poor chemical stability.So people select new catalytic activity agent again, develop multi-functional fuel oil additive.As Patent Office of the People's Republic of China on December 24th, 1997 bulletin number of patent application be 97103979, name is called the application for a patent for invention technology of " fuel oil additive with combustion-supporting, fuel-economizing, purifying functions ".Contain butyl glycol ether, fatty acid ester, ethylene dichloride, butanols, cobalt naphthenate, fatty amide, carboxyethyl germanium sesquioxide in this fuel oil additive.Should affirm that this is to developing the once trial of multi-functional fuel oil additive.
The content of invention
Of the present invention is at the deficiencies in the prior art, provides a kind of active constituent to be soluble in fuel oil and catalytic activity height, dispersiveness and chemical stability are good, cost is lower, has the smoke-eliminating combustion-aid additives for fuel oil of combustion-supporting and oil-saving, pollution abatement effect.
A kind of smoke-eliminating combustion-aid additives for fuel oil, the weight percent of its composition is: oil solubility nanometer iron 1-10%, cobalt naphthenate 5-25%, barium naphthenate 10-30%, polyisobutene succinimide 5-10%, longer chain fatty acid 1-5%, surplus is a solvent.Adding nanometer iron and cobalt naphthenate are made the catalytic combustion-supporting active ingredient in the composition of the present invention, produce a large amount of hydrocarbon free radicals when making oil inflame, and oxidation rate is accelerated, and it is more complete to burn, thereby improve efficiency of combustion, and saving fuel oil effect is obvious, can reach 5-20%.
The present invention adopts barium naphthenate as smoke suppressor, and it can reduce the idle generation of cigarette, can reduce soot emissions 30-60%.Barium naphthenate can substitute with calcium naphthenate or manganese naphthenate or magnesium naphthenate.
The present invention adopts polyisobutene succinimide as detergent-dispersant additive, it can reduce the carbon distribution 30-60% in burner noz(zle) or the oil-firing boiler burner hearth, make engine and the oil-firing boiler good running status that keeps clean, reduce frequency of maintenance, prolong the work-ing life of engine and oil-firing boiler.Polyisobutene succinimide can substitute with trolamine or diethanolamine or thanomin or diethylenetriamine or triethylene tetramine or triethylamine or polyethylene polyamine.
Described a kind of smoke-eliminating combustion-aid additives for fuel oil, the solvent in its composition are alkylbenzene or dimethylbenzene or toluene or benzene or No. 0 diesel oil.The various active constituent chemical stabilities that the present invention adopts are good, are soluble in various oils solvents.
Described a kind of smoke-eliminating combustion-aid additives for fuel oil, in solvent, add cobalt naphthenate, barium naphthenate, oil solubility nanometer iron and longer chain fatty acid at normal temperatures successively according to above proportioning, add polyisobutene succinimide after stirring again and stir.Blending process of the present invention is fairly simple, be easy to promote mix with corresponding fuel oil after, can stable for extended periods of time, no flocks, no colloid.Can be in 1 during use: 1000-1: 2500 ratio directly adds in diesel oil or the heavy oil, need not change the oil supply system of the oil piping system or the oil-firing boiler of vehicle, and be very convenient.
