Abstract

This invention discloses a method for preparing biodiesel oil from animal and plant oils. The biodiesel oil is a new energy with such advantages as simple process, low carbon content, high oxygen content, adequate combustion. The method does not produce any wastewater, water gas or waste liquid, thus has no pollution.

Description

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

Technical field

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

Background technology:

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.May calendar year 2001, television station of central authorities interrogated in the world the program, broadcasted the U.S. for solving the energy and environmental issue, produced biofuel with vegetables oil.Substitute the diesel oil of using refining of petroleum with biofuel.But because present diesel engine speed height, power are big, and progressively become direct injection combustion chamber by divided combustion chamber.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 are disconnected mutually occurs.

Summary of the invention:

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, the i.e. biofuel of producing with animal oil, vegetables oil.

Content of the present invention is achieved in that and with Tai-Ace S 150 vegetables oil is purified earlier.Tell colloid and impurity, then, vegetables oil, butanols, sulfuric acid after purifying carried out transesterification reaction, reflect thick monoesters, fractionate out 170 ℃ through fractionation--the smart monoesters (1) of 360 ℃ of stream sections, as standby.With Tai-Ace S 150 animal oil is purified, isolate colloid and impurity, the animal oil after will purifying is then received with methyl alcohol, methyl alcohol and is reflected thick monoesters, and through fractionation, the smart monoesters that fractionates out 170 ℃-360 ℃ stream sections is smart monoesters (2) with thick monoesters.

With smart monoesters (1) 30%, smart monoesters (2) 50%, alkane (C ₁₀H ₂₂) stream section 20% (weight ratio) synthesize biofuel, enters the finished product jar after the pressure filter press filtration.

With the biofuel that animal oil, vegetables oil are 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.

Description of drawings:

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

Embodiment:

Specify preparation method below in conjunction with accompanying drawing:

Press the process flow sheet of Fig. 1, produce smart monoesters (1), at first vegetables oil is purified, remove colloid and impurity, with the vegetables 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, colloid with bottom, impurity is separated, as bio-feritlizer, and the vegetables oil after again the upper strata being purified, butanols, sulfuric acid adds in the reactor 2 by 1: 1.2: 0.01 (weight ratio), the sealing charging opening carries out transesterification reaction at 120 ℃-130 ℃, stir, reflux through condenser 3, dehydration is till exclusion is deviate from, through neutralization, washing is evacuated to butanols jar 4 with excessive butanols by vacuum pump 5, static 4 hours, the glycerol of reactor 2 lower floors is told, and the thick monoesters that the upper strata has been transformed adds separation column 6, fractionates out 170 ℃-360 ℃ stream sections, heavy constituent at the bottom of the tower are emitted, be used for soapmaking, through decompression, with the smart monoesters of fractionate out 170 ℃-360 ℃ stream sections after water cooler 7 coolings, be smart monoesters (1), enter synthesis tank 8.

Process flow sheet by Fig. 1 is produced smart monoesters (2) 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 ℃, add oil mass 1% then, the Tai-Ace S 150 of content 30%, stirred 30 minutes, be incubated static 24 hours, with the colloid of bottom, impurity is isolated, as bio-feritlizer, with 785 kilograms of adding reactors of upper strata absolute oil, 2 inner sealing charging openings, stirring also is warming up to 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, and the monoesters that the upper strata has been transformed adds separation column 6, fractionates out 170 ℃-360 ℃ stream sections, heavy constituent at the bottom of the tower are emitted, be used for soapmaking.The smart monoesters of 170 ℃-360 ℃ stream sections that go out through vacuum fractionation are smart monoesters (2) after water cooler 7 coolings, enter synthesis tank 8, by smart monoesters (1) 30%, smart monoesters (2) 50% alkane (C ₁₀H ₂₂) flow in the section 20% adding synthesis tank 8, stirring synthesized biofuel in 10 minutes in jar 8, after pressure filter 9 filters, entered finished product storage tank 10 then.

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