Description

A kind of preparation process of bio-fuel
Technical field
The invention belongs to technical field of fuel preparation, more particularly to a kind of preparation process of bio-fuel.
Background technology
Bio-fuel (Biodiesel) is a kind of more clean artificial oil, is commonly used to tractor, truck, ship etc.. It refers to oil crops such as soybean, rape, cotton, palm etc., the water plant such as Wild oil plant and engineering microalgae grease with And animal fat, food garbage oil etc. for feedstock oil by made of ester exchange or thermochemical processes can replace petrifaction diesel again Natural disposition diesel fuel.
Bio-fuel is one kind of biomass energy, it is approached in physical property with petrifaction diesel, but chemical composition is different. Bio-fuel is the mixture of the high complicated organic principle of oxygen content, these mixtures are mainly big organic of number molecular weight Thing, the almost oxygen-bearing organic matter including all kinds, such as：Ester, ether, aldehyde, ketone, phenol, organic acid, alcohol etc..
Bio-fuel in use there are the problem of one of be that condensation point is higher, high condensation point is full at a lower temperature Crystallize and separate out with fatty acid ester, limit the mobility of fuel, and the good fluidity of fuel is to ensure that various equipment are well run It is necessary.In the prior art, the alcohols for having the low condensation point of research and utilization is added in bio-fuel, to reduce the solidifying of bio-fuel Point and cold filter plugging point, improve the cryogenic property of bio-fuel.But the change of alcohols ratio can also reduce the Cetane number of diesel oil, and Cetane number, which reduces, to cause ignitability to be deteriorated, combustion lag, and engine behavior is rough.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of preparation process of bio-fuel, and obtained bio-fuel is each Aspect meets five biodiesel technology requirement of state, and some aspects are even also advantageous over five biodiesel technology requirement standard of state.
To achieve the above object, the present invention adopts the following technical scheme that：
The present invention provides a kind of preparation process of bio-fuel, including following preparation process：
1) fatty acid methyl ester is taken, adds alcohols, is uniformly mixed；
2) it is put into pressure pan, in 3-8kgf/cm2Under pressure, 20-30min is handled；
3) the microwave treatment 30-60s under 200-400W again；
4) stirred evenly under 600-900r/min rotating speeds.
Alcohols of the present invention is octanol and the mixture of isopropanol.
Preferably, in step 1) of the present invention, the alcohols is 10-20 parts by weight octanol and 3-8 parts by weight isopropyls The mixture of alcohol.
Preferably, in step 1) of the present invention, the alcohols is the mixed of 15 parts by weight octanols and 6 parts by weight of isopropyl alcohol Compound.
Preferably, in step 1) of the present invention, the volume ratio of alcohols and fatty acid methyl ester is 8-13:1.
Preferably, in step 2) of the present invention, the temperature for controlling pressure pan is 40-50 DEG C.
Preferably, in step 2) of the present invention, the microwave treatment 45s under 300W.
Compared with prior art, the beneficial effects of the present invention are：
1st, alcohols is added in fatty acid methyl ester in the method for the present invention, by the method for the present invention, life can be significantly improved The condensation point and cold filter plugging point of thing fuel, and improve low temperature flow.
2nd, by the method for the present invention, and selection and the ratio of the species of alcohols are controlled, is significantly improving bio-fuel Condensation point and cold filter plugging point, and low temperature flow is at the same time, Cetane number will not be caused to reduce.
3rd, other performances of the bio-fuel that the method for the present invention is prepared disclosure satisfy that five biodiesel technology of state of bio-fuel It is required that.
