Abstract
The invention relates to water/hydrocarbon emulsion fuel. The addition amount of an emulsifier accounts for 0.03-0.5% of total weight of the fuel, the addition amount of water accounts for 3-35% of the total weight of the fuel, the emulsifier at least comprises isosorbide accounting for 25-45% of the total weight of the emulsifier, fatty acid ester or ricinoleate accounting for 15-25% of the total weight of the emulsifier, and polyoxyalkylated alkylphenol accounting for 5-20% of the total weight of the emulsifier. The emulsion fuel is better in stability, the rate of fuel saving is higher, and emission is less.
Description
Technical field
The present invention relates to water/water/hydrocarbon emulsified fuel.
Background technology
In later stage nineteen fifties, the contradiction of environment and development is day by day obvious, and oil crisis begins to occur.The efficiency of combustion that save and use fuel, improves fuel becomes the problem of people's primary study and concern, and wherein, the fuel technology for mixing water that possesses the dual function of energy-saving and pollution-reducing is subject to extensive concern and exploitation, and has obtained positive effect.
Water under normal circumstances, is to merge mutually with the fuel that is comprised of the non-polar compound hydro carbons as polar compound.A phase uniform liquid is dispersed in another phase liquid in order to incite somebody to action wherein, makes its mixed solution be metastable state, needs by means of external force or adding emulsifying agent.Thisly merged the mixed solution that forms by fuel (such as kerosene, gasoline, diesel oil, heavy oil, residual oil etc.) with the water that comprises emulsifying agent and just be called as emulsion fuel.Atomizing state when emulsion fuel can improve fuel combustion improves the efficiency of combustion of fuel, thereby reaches the purpose of fuel-economizing.
It is great adopting the meaning of emulsion fuel.Take heavy oil as example, heavy oil is widely used in industrial every field as industrial basic fuel, and at present, the annual heavy oil of fuel that is used as of China is more than 4,000 ten thousand tons.Generally all use heavy oil to act as a fuel in many places such as refinery, chemical plant, steelworkss.In recent years, because oil price sharply rises violently, mix mutually to form uniform emulsion fuel by the water that will contain emulsifying agent with heavy oil or tar, and replace original crude oil or heavy oil with this, not only can reduce the cost of enterprise, increase economic efficiency, and because emulsion fuel has the characteristics such as volatility is high, thermal value is large, ash content is few, have especially the advantages such as efficiency of combustion is high, flue dust is few, environmental pollution is little, thereby have good economic benefit and application prospect.
Select the good emulsifying agent can obtain higher rate of economizing gasoline, reduce the discharging of objectionable impurities, thereby obtain the emulsion fuel of more efficient, energy-conservation and environmental protection, therefore, choose emulsion agent and water and emulsifying agent are carried out suitable proportioning is committed step indispensable in the making processes of emulsion fuel.
Summary of the invention
The invention provides a kind of water/water/hydrocarbon emulsified fuel, have better stability, higher emulsification degree, and have higher rate of economizing gasoline and discharge still less.
In order to realize above-mentioned technical purpose, the present invention proposes a kind of water/water/hydrocarbon emulsified fuel, wherein, the addition of emulsifying agent is the 0.03%-0.5% of fuel gross weight, the addition of water is the 3%-35% of fuel gross weight, and described emulsifying agent comprises the sorbitol ester that accounts for emulsifying agent gross weight 25%-45% at least, the poly-alkoxylation alkylphenol that accounts for fatty acid ester or the ricinoleate of emulsifying agent gross weight 15%-25% and account for emulsifying agent gross weight 5%-20%.
Optionally, described emulsifying agent comprises at least: the stearate and the weight ratio that account for the Arlacel-83 of emulsifying agent gross weight 25%-35% or its analogue, derivative or its combination, weight ratio and be 15%-25% are the octyl phenol of 5%-10%.
Optionally, also contain oil fuel in described water/water/hydrocarbon emulsified fuel, described oil fuel is following one or a combination set of: crude oil, heavy oil, normal vacuum residuum, Catalytic Cracking Residual Oil, coking sump oil, esterification or no esterification plant or animal oil.
Optionally, described water/water/hydrocarbon emulsified fuel also contains additive.
Optionally, described additive is frostproofer, water quality stabilizer and ignition dope.
Compared to prior art, water/water/hydrocarbon emulsified fuel of the present invention can obtain higher rate of economizing gasoline and satisfactory stability, and can greatly reduce the discharging of objectionable impurities, reduces flue dust.
