Abstract
The invention provides a method for preparing biodiesel by using castor oil, and relates to a base catalysis method for preparing the biodiesel by using the castor oil as a raw material. The method comprises the step of reacting the castor oil and alcohol at a temperature of between 45 and 65 DEG C for 1.5 to 6 hours in the presence of catalyst so as to obtain the biodiesel, wherein the molar ratio of the castor oil to the alcohol is 1:6; and dosage of the catalyst is 0.8 to 1 percent of the oil by weight. Through an ester exchange reaction of the castor oil, the method reduces the viscosity of the castor oil, improves the flowability of the castor oil, improves volatility of fuel, and has simple and feasible production process and low cost; and products obtained by the method can be directly used in a diesel engine. The method has high yield of biodiesel, general esterification ratio over 96 percent, short reaction time, low cost, reproducible raw materials, wide applicability and simple post-treatment.
Description
Technical field
The present invention relates to the renewable energy source domain, belong to the green chemical industry process, is a kind ofly to prepare the biofuel method with Viscotrol C.
Background technology
Biofuel is meant and comes from the material that biological product can be used as diesel-fuel, comprises fatty acid ester that the crackate of vegetable and animals oils or animals and plants and short chain alcohol transesterify obtain etc.Because the carbochain of vegetables oil is long, it is many or contain reasons such as side chain is many to contain undersaturated pair of key, makes its viscosity too high; Discarded food oils source is complicated, and various one-tenth split poles are fixing, and become sour, go mouldy, factor such as a large amount of impurity; Higher in the animal grease as commercial size lard acid number, often be mixed with than juicy, impurity such as protein, phosphide, colloid etc.All these renewable resourcess all must carry out modification with chemical process, increase the mobile and reduction viscosity of oil product, make it become biofuel.
At present biofuel is mainly carried out transesterification reaction with animal and plant grease and methyl alcohol or ethanol under acidity or basic catalyst and certain temperature, generate corresponding fatty acid methyl ester or ethyl ester, through washing drying, promptly get biofuel again, obtain by-product glycerin simultaneously.Although the technology of chemical method production biofuel reaches its maturity, but still there is shortcoming, as arts demand optimization, production process reduces the discharging alkali wasteliquid as far as possible, simultaneously because reaction is to carry out at methyl alcohol and oily biphase phase interface, rather than homogeneous reaction, so speed of response is slow, shortcomings such as long reaction time.
Summary of the invention
The objective of the invention is provides a kind of and prepares method of bio-diesel oil with Viscotrol C in order to overcome above-mentioned technical disadvantages.This method: with Viscotrol C and pure mol ratio 1: 6, catalyst levels was the heavy 0.8-1% of oil, and 45-65 ℃ of reaction 1.5-6h down can get biofuel.The present invention has reduced the castor-oil plant oil viscosity by the Viscotrol C transesterification reaction, improves its flowability, improves fuel volatility, and production technique is simple and easy to do, and cost is low, and products obtained therefrom can directly use for diesel engine simultaneously.The yield of biodiesel height, general esterification yield can reach more than 96%, and the reaction times of the present invention is short, and cost is low, and raw material is renewable, wide adaptability, aftertreatment is simple.
To achieve these goals, technical scheme of the present invention is to realize like this.
With Viscotrol C is raw material, it is characterized in that with Viscotrol C be the feedstock production biofuel, and with Viscotrol C and pure mol ratio 1: 6, catalyst levels was the heavy 0.8-1% of oil, and 45-65 ℃ of reaction 1.5-6h down can get biofuel.
Relevant processing condition in the above-mentioned technology:
1, transesterification reaction: with Viscotrol C and pure mol ratio 1: 6, catalyst levels was the heavy 0.8-1% of oil, and 45-65 ℃ of reaction 1.5-6h down can get biofuel.
2, catalyst preparation: the alkaline catalysts consumption accounts for the 0.8-1% of the massfraction of seed kernel oil, and it is dissolved in the alcohol, and it is stand-by to form saturated solution.
The present invention has the following advantages:
1, adopts transesterification reaction, reduced reacting balance time, the yield of biodiesel height.
The present technique gentleness prepare the reaction conditions of biofuel with Viscotrol C.
3. esterification yield can reach more than 95%.
4. the present technique reaction times lacks, and cost is low, and raw material is renewable, wide adaptability, and aftertreatment is simple.
