Description
Technical field
The xylogen shortening cracking that the present invention relates to biomass resource prepares the method for aromatic compound, and especially a kind of xylogen catalytic pyrolysis generates the method for aromatic compounds such as phenylol, pockwood phenolic group or Syringa oblata Lindl. base.
Background technology
Continually developing and consuming of fossil resources such as oil produces the shortage of energy chemical and a series of environmental problems.The new resources route of development and utilization recyclable regenerative becomes the inexorable trend of social development.Biomass are a kind of natural resourcess capable of circulation, and wide material sources are abundant at the occurring in nature reserves, are very one of the renewable resourcess of fossil resource such as potential alternative oil of a class.Aromatic compound has important application in the human being's production practical activity.As benzene and phenol derivmives blend biology, be not only widely used bulk chemical, simultaneously also be the important intermediate compound of producing polymkeric substance, medicine intermediate and fine chemical product such as resin.Therefore, how to utilize biomass resource effectively and rationally, the aromatics that preparation has significant application value receives the very big concern of scientific circles and industry member.
Xylogen content in biomass resource is only second to Mierocrystalline cellulose, be one of the abundantest Biological resources of nature, but, the conversion and the utilization of xylogen have been limited because complex structure, unreactiveness, the converted product of xylogen are difficult to a series of difficulties such as separation and purification.The waste liquid that existing paper industry produces, the wherein contained xylogen more than 95% are directly discharged or are concentrated the back and burned, and cause water body, soil and atmospheric pollution, the havoc mankind's living environment.Compare with other biomass, the unique distinction of xylogen is that it contains a large amount of available aromatic ring structures.Therefore, rationally utilize a large amount of aromatic rings in the xylogen resource efficiently, not only can obtain the aromatics of high added value, make energy chemical for non-fossil resource a new approach is provided; Reduce discharging wastes and pollute, for saving petroleum resources and environment protection, significant.
Xylogen is the effect that plant materials passes through enzyme, and the three-dimensional netted polymer of a class with the polymerization of phenyl-propane basic structural unit forms is present in the cell walls of plant materials with the association of Mierocrystalline cellulose hemicellulose.On structure, xylogen mainly contains three kinds of elementary cells, i.e. guaiacyl, Syringa oblata Lindl. base and p-hydroxybenzene, and these three kinds of unit mainly are coupled to each other by ehter bond and form, and this bind mode accounts for 2/3～3/4 of all bind modes.By design and preparation appropriate catalyst, the ehter bond in the xylogen that efficiently, optionally ruptures is the key of preparation aromatics.This direct catalytic thermal cracking method has reaction product concurrently and distributes according to qualifications and advantage of low energy consumption.
Because the complex construction and the unreactiveness of xylogen, the research report that relevant its catalytic pyrolysis utilizes is still rare.World patent (WO99/10450) has been described at 260-310 ℃ and has been utilized alkali to make lignin depolymerization, is the process of gasoline component with lignin conversion carrying out hydrotreatment more than 350 ℃.This technology can be a fuel with lignin conversion, but the method cracking process needs more hydrogen source with the complete hydrogenation of the phenyl ring of xylogen; Two stage conversion process strengthens energy consumption, and a large amount of mineral alkalis of use then are easy to generate environmental pollution.United States Patent (USP) (US 4,900,873) has been reported at 300-400 ℃ and has been used aromatic compounds such as biphenyl or naphthalene to decompose xylogen as solvent thermal down, produced aldehydes matters such as cresols.This process productive rate is lower, less than 20%; The capacity usage ratio of pyrolytic process is low.Canadian Patent (CA 700,210) has been described xylogen and has been used metallic sulfide to be the Preparation of Catalyst phenolic compound under 250-450 ℃ and 15MPa～45MPa condition.This process reaction condition harshness, temperature, pressure is excessive.Chinese patent (CN 1201778A) has been described the method that obtains syringaldehyde and vanillin food grade,1000.000000ine mesh by the alkali oxide lignin, but the product that this method obtains is other chemical, can't obtain pockwood phenols and Syringa oblata Lindl. base class aromatic compound product that alkyl replaces.
Up to the present, the aspect that utilizes of xylogen mainly exists problem:
Xylogen be this as superpolymer, be connected with chemical bond with the glycosyl of plant materials hemicellulose usually, not easily separated purification, the while xylogen macromolecular chain of curling makes that catalyzed reaction is difficult to carry out, and presents the chemical reaction inertia;
2. this of xylogen kind of constructional feature strengthens the conversion process energy consumption, severe reaction conditions, and conversion rate of reaction product is low;
3. the conversion of xylogen often makes phenyl ring excessive hydrogenation on its chain, so need more hydrogen source, Atom economy is low.
4. it is noble metal catalysts such as Pt, Ru that present document reports xylogen hydrogenation catalyst system therefor, does not see cheap Ni catalyst hydrogenation cracking xylogen.Ni is catalyst based to be cheap hydrocracking catalyst, but temperature of reaction is usually more than 350 ℃, the energy consumption height.Therefore need reduce energy consumption of reaction by designing new catalyst system.
Summary of the invention
The object of the present invention is to provide a kind of from xylogen prepare aromatic compound novel method, produce aromatics for non-petroleum path new way be provided, with the shortage of alleviating fossil resources such as oil to producing the negative impact that chemical causes.The new way of being carried is catalyst based and have under the acting in conjunction of the small molecules solvent that forms the hydrogen bond ability by Ni, natural lignin or industrial lignin highly effective hydrogenation cracking generation aromatic compound, especially Syringa oblata Lindl. base and guaiacyl compound.This method transformation efficiency height, mild condition, catalyzer is cheap and have a very high selectivity of product.
