Abstract
The invention relates to biodiesel prepared by non-edible vegetable oil and a method thereof, which belong to the biodiesel field. By-product milk thistle oil produced during the production process of Silibinin serves as a raw material for preparing the biodiesel. The biodiesel is obtained by transesterification of the milk thistle oil and methyl alcohol under the condition of a catalyst. Gas chromatography-mass spectrometry analysis results show that main components of the biodiesel prepared by the milk thistle oil serving as the raw material are methyl oleate and methyl linoleate. The biodiesel is high in cetane number, excellent in performance and capable of meeting China current biodiesel standard. In addition, the biodiesel is simple in process, mild in reaction condition, low in cost and capable of achieving large-scale production.
Description
Technical field
The present invention relates to a kind of biofuel and method thereof of novel non-edible plant oil preparation, be specifically related to the biofuel and the method for a kind of medication plant by-products-non-edible Silymarin oil preparation, belong to field of biodiesel oil.
Background technology
Oil has greatly promoted modern civilization as a kind of valuable source of the world today, for huge contribution has been made in the mankind's life.But Along with people's makes the reserves of this Nonrenewable resources of oil reduce day by day to the demand sharp increase of petroleum chemicals, has the expert to foretell that oil will be exhausted in coming few decades.Biofuel has caused people's extensive concern with its abundant raw material sources, the outstanding feature of environmental protection and good recyclability.It is the New-type fuel that utilizes the clean and safe that animal-plant oil and high-acid value grease etc. produce, and mainly is to utilize these greases and some short chain alcohol (methyl alcohol, ethanol etc.) under the catalyzer condition, catalyzed transesterification to take place and produce.Ester-interchange method is divided into acid-base catalysis method, overcritical ester-interchange method and catalyzed by biological enzyme again.Acid-base catalysis method cost is low, and reaction conditions is gentle, and technology is simple.Patent CN101503629 discloses " a kind of method of preparing biodiesel from lipid under supercritical condition " on August 12nd, 2009, and this method is higher to matching requirements; Patent CN101113354 discloses " a kind of preparation method of environment-friendly type biodiesel " on January 30th, 2008, this method needs expensive katalaze(enzyme).
At present, soybean and rape are the main raw materials of production biofuel in the world, are raw material with the VT 18 like the U.S., and rapeseed oil is then used in Europe, but are that the raw material of feedstock production biofuel will certainly aggravate global grain race problem with the edible oil.Therefore, each state all can develop the inedible oil plant resources of biofuel in positive searching.Silymarin (Silybum marianum) is annual or 2 years these plants of sward, and all there are a large amount of plantations in China Shaanxi, Gansu, Heilungkiang, Hebei etc., produces the fruit total amount per year and can reach more than the 2000t; And contain significant quantities of fat in the Silymarin fruit, content reaches about 30%, and [Qian Xue penetrates, Zhang Weiming; Turn round and look at Gong's equality. be worth the Silymarin oil [J] of development and utilization. Chinese wild plant resource; 2006,25 (5), 13-16].Be it to be squeezed the back of deoiling extract flavones ingredient-SLB wherein to the topmost purposes of Silymarin fruit at present, be used for field of medicaments, Silymarin oil is that it produces by product; Though higher industry and pharmaceutical value are arranged, in the squeezing process course of processing, pigment, fiber, wax and some other compositions produce very big influence to oil; Need can use through after the refining [Xu Defeng, Zhang Weiming, history sturdy pines etc. domestic Silymarin utilization of resources status and prospects [J]. food research and development; 2007; 28 (2), 157-160], so Silymarin oil also is not utilized effectively at present.Discover; Contain in the Silymarin oil a large amount of unsaturated fatty acidss [Li Hongying, Fang Hong is strong. the assay of four kinds of lipid acid [J] in the Silymarin oil. foodstuffs industry science and technology, 2010; 7; 360-362], the fatty acid methyl ester that after esterification, obtains has lower viscosity, and is suitable to motor spirit.Therefore adopt non-edible Silymarin oil to have prospect preferably, but also do not see relevant research report and patent at present openly for the raw material production biofuel.
Summary of the invention
Based on the deficiency that exists in the above background technology, the object of the present invention is to provide a kind of is the biofuel and the method thereof of feedstock production with novel non-edible plant oil-Silymarin oil.
The present invention is to be the feedstock production biofuel with the by product Silymarin oil in the SLB production process, be by Silymarin oil and methyl alcohol under the catalyzer condition, pass through a kind of biofuel that transesterification reaction obtains.Gas chromatography-mass spectrometry analysis is the result show; The staple that with Silymarin oil is the biofuel of feedstock production is Witconol 2301 and methyl linoleate; This is similar with the staple of the biofuel of sunflower oil preparation with VT 18 of bibliographical information [Mar í a Jes ú s Ramos, Carmen Mar í a Fern á ndez, Abraham Casas et al.. Influence of fatty acid composition of raw materials on biodiesel properties [J]. Bioresource Technology; 2009.100.261-268]; See table 1, can substitute edible oil, effectively solve the contradiction between the grain and the energy.
