Description
Technical field: the present invention relates to a kind of is the biofuel and the production method of raw material production with the plant seed oils, being particularly related to a kind of Semen Euphorbiae oil biofuel with the seed oil preparation of Semen Euphorbiae (seed of euphorbia plant Euphorbia lathyris Euphorbiala thylris L.), is raw material through biofuel of Catalytic processes preparation and preparation method thereof with Semen Euphorbiae oil and methyl alcohol.
Background technology: in recent years, along with the exhaustion day by day of fossil fuel, biofuel has caused the extensive concern of countries in the world.2007,1.986 hundred million tons of China's oil net importations, import interdependency 51.3%, and the import interdependency is in rising trend.The biofuel overwhelming majority derives from vegetables oil, and except that can effectively alleviating the exhausted pressure of fossil fuel, evaluation of life cycle shows that photosynthesis can make the utilization of biofuel that Greenhouse effect are minimized.Studies show that raw materials cost almost accounts for 75～80% of biofuel total cost, so the selection of cheap oil plant, utilize and to have become the general character gordian technique that breaks through the production of biodiesel technical bottleneck.Being extensive use of the national many of biofuel is raw material with edible oil (soybean oil, rapeseed oil, sunflower oil), government finance subsidy and reduction or remission of taxes are that the edible fat production biofuel is extensive use of in these countries, but use edible oil to prepare biofuel and brought a series of problems, wherein serious is the grain security problem.
At present world's biofuel industry development process bottleneck of generally acknowledging is that the expensive final product price that causes of raw material is higher, can't be directly and fossil fuel carry out market competition.Along with the development of biofuel industry, non-grain and oil material crop has become the reasonable raw material that generally acknowledge countries in the world, and will study focus and turn to non-grain and oil material crop resource, and present non-grain and oil material crop species is few, kind is more single.
Semen Euphorbiae (Euphorbia lathyris L.) has another name called Euphorbia lathyris, and its seed oil content is more than 40%.Professor M.Calvin of California, USA university thinks that by to not belonging to the evaluation study that oil plant carries out the energy utilization potentiality together it is a kind of novel energy oil crops that the exploitation future is arranged very much.Danger Wen Liang etc. analyzes the Semen Euphorbiae oil lipid acid composition on Anhui, Henan, three ground, Fujian respectively, finds that its main lipid acid is oleic acid, reaches more than 83%, all the other are (danger Wen Liang such as palmitinic acid, stearic acid, arachidonic acid, linolic acid, linolenic acid, Jin Mengyang, Ma Chong, etc.Euphorbia lathyris fatty acid oil compositional analysis [J], Chinese oil, 2007,32 (5): 70-71).The Euphorbia lathyris fatty acid oil is formed with the molecular composition of desirable diesel oil substitute similar, is one of desirable feedstock of China's development biofuel.
Non-grain and oil material crop---Semen Euphorbiae is based oneself upon in this patent invention, for the new non-grain and oil material of biofuel industry development source, replenishes as the non-grain and oil material of biofuel industry crop.Semen Euphorbiae is short vegetative period, strong stress resistance, reproductivity is strong, wide material sources (originating in ground such as Jilin, the Inner Mongol, Liaoning, Hebei, Shaanxi, Gansu, Xinjiang, Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, Henan, Hubei, Hunan, Guangxi, Sichuan, Guizhou, Yunnan, Tibet).And have patent report can and Cortex jatrophae between plant (Yuan Lichun, Yang Shunlin, Zhang De, etc., the method for planting between a kind of Euphorbia lathyris and Cortex jatrophae [P] CN101283657), can improve land utilization ratio, potential economic benefit and obvious social benefit.
At present, be that raw material production Semen Euphorbiae oil biofuel and method thereof still are not reported with the Semen Euphorbiae oil.
Summary of the invention: the object of the invention is to provide a kind of new, practicable non-grain and oil material as biodiesel raw material and production technique thereof, particularly is main material production Semen Euphorbiae oil biofuel and production method thereof with the Semen Euphorbiae oil.
The present invention is a kind of Semen Euphorbiae oil biofuel with the preparation of the seed oil of Semen Euphorbiae, be with Semen Euphorbiae oil and methyl alcohol be raw material under the catalyzer existence condition, prepare method of bio-diesel oil through catalyzed reaction.
Concrete scheme of the present invention is as follows:
1. remove the Semen Euphorbiae oil of mechanical impurity after filtration, with methyl alcohol, single or composite catalyst input reaction kettle for reaction, after reaction finished, reaction system got biofuel after separation and purification treatment.Wherein, catalyst levels is 0.5～8% of an oil plant quality, and the oleyl alcohol mol ratio is 1:3～1:20, and temperature of reaction is 55～70 ℃, and the time is 0.5～3h.
