Abstract

The invention is a producing technique of micro-emulsified fuel and the formula. Its character: according to the weight percentage, emulsifying agent 6-9%, fuel 70-80%, purified water 15-20% and assistant 0.4-0.7%, mix them and fully stir to make the micro-emulsifier fuel. It adopts the micro-emulsifier techinque. It can alone be used and also mixed with similar fuel for use.

Description

Micro emulsion fuel production process and prescription

Affiliated field

The invention belongs to the production technique and the prescription in fuel oil field, particularly a kind of emulsified fuel.

Background technology

For saving oil, have the production technique of various emulsified fuels or petroleum supplements and prescription to come out one after another at present, but its product, no matter after calorific value, production cost, the burning in the tail gas objectionable constituent content, colourity etc. all not ideal enough,

Summary of the invention

The object of the invention just provides a kind of production technique and prescription of micro-emulsified fuel, makes the emulsified fuel cost low, and objectionable constituent content is low in the tail gas of burning back, the micro-emulsified fuel of economical and environment-friendly type.

Production technique of the present invention and prescription be, with emulsifying agent, purify waste water, auxiliary agent, kerosene or diesel oil mixes and fully stir and form, its each component is by weight ratio, emulsifying agent is 6-9%, purifying waste water is that 10-20%, auxiliary agent are 0.4-0.9%, and kerosene or diesel oil are 70-80%.Emulsifying agent is to be mixed and fully stirred by sapn, tween, peregal, oleic acid, naphthenic acid to form in about 10 minutes, and its weight proportion is, sapn is 7-15%, and tween is 1-4%, and the average 1-4% that adds as, oleic acid are 1-2%, and naphthenic acid is 75-90%.Auxiliary agent is to be mixed by Virahol and quadrol, and fully stirs about 10 minutes and form, and its weight proportion is, Virahol is 10-40%, and quadrol is 60-90%.Purifying waste water is to sneak into 8 ‰ alkali in water, and fully stirs about 10 minutes formulated.

At normal temperatures and pressures, by proportioning emulsifying agent is mixed with kerosene or diesel oil, and fully stir about 20 minutes, add again and purify waste water, fully stir again about 20 minutes, add auxiliary agent again, after fully stirring about 20 minutes again, just make microemulsified kerosene or micro emulsion diesel fuel.

Because what the present invention adopted is micro-emulsion technology, form the short grained water-in-oil shape of 0.005-0.02 μ m solution, this solution micella grain has reached nano level, less than wavelength of visible light, so micellar solution is transparent, between the profit no interface, also there is not interfacial tension.Its product free from extraneous odour, not stratified, do not precipitate, sufficient combustion, production cost are low, objectionable constituent content is low in the tail gas after the burning, this product can use separately also can mix with similar oil and use.

Description of drawings

Accompanying drawing is the technological process of production figure of micro-emulsified fuel.
