Abstract

The method for producing biological diesel oil by using animal fat includes the following steps: heating and cleaning animal fat by using aluminium sulfate, making cleaned animal fat react with solution of methyl alcohol and methyl alcohol sodium to obtain crude monoester, making the crude monoester undergo the process of fractional distillation at 170-360 deg.C to obtain refined monoester, mixing the refined monoester and paraffinic hydrocarbon (C10H22) to synthesize biological diesel oil, filtering by press-filtering machine and placing said finished producing into storage tank. The cetane value of said biological diesel oil is up to above 45, its carbon content is low, oxygen content is high, its combustion is complete and cost is low.

Description

A kind of biofuel and preparation method of producing with animal oil

The present invention relates to a kind of method of producing oil fuel with animal oil.

At present, the diesel oil that countries in the world are used all extracts with refining of petroleum.But because the consumption of oil increases year by year, the underground storage of oil reduces day by day.For solving the energy and environmental issue, countries in the world are all in the research alternative fuel.In May calendar year 2001, the Chinese Central Television (CCTV) interrogates in the world the program, broadcasts the U.S. for solving the energy and environmental issue, produces biofuel with vegetables oil, substitutes the diesel oil of using refining of petroleum with biofuel.But, use that the viscosity that biofuel that vegetables oil produces brings is big, problems such as colloid is high, cetane value is low, cost height occur in succession because present diesel engine speed height, power is big, and progressively becomes direct injection combustion chamber by divided combustion chamber.

The purpose of this invention is to provide that a kind of carbon content is low, oxygen level is high, sufficient combustion, new forms of energy that cost is low, produce method of bio-diesel oil with animal oil.

The object of the present invention is achieved like this: with Tai-Ace S 150 animal oil is purified earlier, tell colloid and impurity.Then, the animal oil after purifying is reflected thick monoesters with methyl alcohol, sodium methylate, thick monoesters through fractionation, is fractionated out the smart monoesters of 170 ℃-360 ℃ stream sections, with smart monoesters and alkane (C ₁₀H ₂₂) stream section synthesizes biofuel, enters the finished product jar after the pressure filter press filtration.

With the biofuel that animal oil is produced, cetane value is more than 45, and carbon content is low, oxygen level is high, sufficient combustion, pollution emission is little, cost is low, raw material sources are extensive, is a kind of new forms of energy of having great potentialities.

Specify preparation method below in conjunction with accompanying drawing:

Fig. 1 is a process flow sheet of producing biofuel with animal oil:

At first animal oil is purified, remove colloid and impurity.With the animal oil heating tank 1 of packing into, and heat temperature raising to 60 ℃, then, add the Tai-Ace S 150 of oil mass 1%, content 30%, stirred 30 minutes, be incubated static 24 hours, the isolated colloid of bottom, impurity are told, be used as bio-feritlizer.Again oil, methyl alcohol are fed intake by 1: 6 mol ratio, in 785 kilograms of adding reactors 2 of upper strata absolute oil, get 250 kilograms of methyl alcohol, add 4 kilograms of sodium methylates after, also add in the reactor 2, the sealing charging opening, stirring also heats up 70 ℃, after 2 hours, excessive methyl alcohol is evacuated to methanol tank 4 by vacuum pump 5 through condenser 3 condensing refluxes, static 2 hours, the glycerol of reactor 2 lower floors is told.The monoesters that the upper strata has been transformed adds separation column 6, and 170 ℃-360 ℃ stream sections of fractionation are emitted heavy constituent at the bottom of the tower, are used for soapmaking.The smart monoesters of 170 ℃-360 ℃ stream sections that will fractionate out through reducing pressure enter synthesis tank 8 after water cooler 7 coolings, add 15% alkane (C again ₁₀H ₂₂) the stream section, stirred 10 minutes, synthesize biofuel, after pressure filter 9 filters, enter finished product storage tank 10 then.

Whole reparation technology does not have waste water, waste gas, waste liquid generation, non-environmental-pollution.

Produce biofuel with the also available vegetables oil of this technical process.

Claims

1, a kind of biofuel is particularly a kind ofly produced method of bio-diesel oil with animal oil, and it comprises the following steps:
