Abstract

A microemulsified fuel oil is prepared from fatty acid (or oleic acid) (15 vol.%), triethanolamine (or biethanolamine) (2 vol.%), isopentanol (3 vol.%), water (20 vol.%) and diesel oil (60 vol.%). Its advantages are low cost, little harmful gas, and long service life of diesel engine.

Description

The production technique of micro-emulsified fuel 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

Oil is the non-renewable energy, for saving oil, there are the production technique and the prescription of the fuel substitute of various emulsified fuels and oil to come out one after another at present, but the every technical indicator of its product, as calorific value, tail gas oxious component content, cost, colourity etc., all not out of this world.Find through further investigation, in the material oily, that the water two-phase is immiscible, add a large amount of tensio-active agent and cosurfactant, make the surface tension of oil, water reduce to extremely low, even reduce to negative value in moment, make whole system spontaneously form translucent or transparent isotropic liquid system, water is dispersed in as disperse phase and forms the W/O microemulsion in the oil, and the liquid pearl radius of this microemulsion is generally 10-100nm, thermodynamics is highly stable, not stratified, do not precipitate, high temperature resistant, easy storage.Tensio-active agent in the prescription of emulsified fuel, to performance, the cost of its product, influence is very big, thinks through experimental study for many years, adopt the tensio-active agent of the tankage generation of the wide vegetable oil production in source, can reduce fuel cost and can improve the fuel oil technical feature again.

Summary of the invention

Purpose of the present invention just provides micro emulsion fuel production process and the prescription that a kind of technology is simple, equipment simple, the tensio-active agent raw material sources are wide, cost is low, product performance index is all excellent.

Production technique of the present invention is: drop into diesel oil, water, lipid acid in the reactor in proportion, 50-60 ℃ of temperature fully stirred 8-12 minute under normal pressure, add trolamine and primary isoamyl alcohol more in proportion, fully stirred again 8-10 minute, promptly can be made into the micro-emulsified fuel finished product.Its each proportion of raw materials (long-pending ratio) is: lipid acid is 10-20%, and trolamine is that 1-2% primary isoamyl alcohol (C=5) is 2-3%, water-oil ratio 1: 3

The simple equipment used of technology of the present invention is simple, raw material sources are wide, utilize the tankage after the vegetable oil production to be emulsifying agent, tensio-active agent, the every index and the ordinary diesel oil of product are close substantially, calorific value reaches the 9000-9300 kilocalorie, cost reduces about 15-20% than ordinary diesel oil, environment protecting is obvious, compare exhaust smoke level with diesel oil and reduce approximately 60%, it is about 50% that obnoxious flavour reduces, and diesel engine is not had corrosion, can reduce carbon distribution, reduce diesel engine operating temperature and noise, prolong diesel engine work-ing life, the tankage of China's vegetable oil production are made full use of.Economic benefit that tool of the present invention is very high and social benefit.

Embodiment

The production technique of micro-emulsified fuel is diesel oil, water, lipid acid to be dropped in the reactor to mix stir about 10 minutes under 50-60 ℃ of temperature normal pressure, drops into trolamine and primary isoamyl alcohol again, and about 10 minutes of restir can go out finished product.By volume, its optimum formula: water is 20%, diesel oil is 60%, lipid acid is 15%, trolamine is 2%, primary isoamyl alcohol is 3%.

Claims
