Description
Technical field
The present invention relates to by hydrogenolysis and the intermolecular condensation method that obtain the catalyzed conversion of middle long chain alkane of glycerol molecule under acidic conditions.
Background technology
The energy is divided into Nonrenewable energy resources and renewable energy source.Nonrenewable energy resources comprise coal, oil and natural gas.Renewable energy source comprises water energy, wind energy, sun power, tidal energy, sea wave energy, Geothermal energy, ocean heat, Hydrogen Energy, nuclear energy, bioenergy.In 2007, global coal turnout was 6.5 * 10
9T, and the amount of whole world coal is 9.09 * 10
11T that is to say if according to this speed, coal only enough 140 years.The a large amount of pollution of the annual discharging in coal power station: 1.1 * 10
7The t carbonic acid gas, 3 * 10
4The t oxynitride, 1.6 * 10
4T sulfurous gas, 1 * 10
3T dust and other a small amount of picture calcium, potassium, the chemical substances such as titanium and arsenic.With the production rate of present oil, global oil at most can only be with 50 years.1996, the reserves of global Sweet natural gas were 1.412 * 10
15m
3, use only more than 60 year.So it is necessary and urgent greatly developing renewable energy source.
The renewable energy sources such as water energy, wind energy, sun power, tidal energy, sea wave energy, Geothermal energy, ocean heat are subjected to the impact of geographical environment very large, and efficient is not high yet.And Hydrogen Energy say in principle can not be as a kind of energy because hydrogen electrolysis from water needs to use a lot of energy in this process, the energy of being emitted by combustion of hydrogen all can not remedy the energy in the electrolytic process.So it is very unpractical replacing top fossil energy by these energy separately.Most potential should be nuclear energy and bioenergy.Bioenergy generally is divided into two classes---first-generation bioenergy and s-generation bioenergy.First-generation bioenergy (such as bio-ethanol and biofuel) is to develop from carbohydrate and vegetables oil; S-generation bioenergy then is to develop from biomass (comprising timber, stalk, grass etc.).The comparative maturity of first-generation Bioenergy development now, carries out transesterify production biofuel with vegetables oil and has obtained significant progress.But in the process of production biofuel, can produce a large amount of glycerin by-products, so the research work around transformation of glycerol has much now, more typically have by glycerine and obtain propylene glycol, such as L.Ma[L.Ma et al.Catalysis Communications, 2008,9:2489-2495] and Yoshinao Nakagawa[Yoshinao Nakagawa et al, Journal of Catalysis, 2010,272:191-194] scheme that proposes, and obtain propenal by glycerine, as the clear people (CN 101426754A) of grade of the wild political affairs of Austria and nearly rattan be good for etc. the scheme that proposes of people (CN 101619019A).
The present invention is a new reaction system, and glycerine can be converted into take middle long chain alkane (carbonatoms is as 6~24) as main oily mater in this reaction system.Because the present invention is converted into final product in the step by glycerine, so this method for transformation of the present invention has very large advantage, is expected at and alleviates to a certain extent following energy dilemma.
Summary of the invention
The purpose of this invention is to provide a kind of by hydrogenolysis and the intermolecular condensation method that obtain the catalyzed conversion of middle long chain alkane of glycerol molecule under acidic conditions.
The method that is obtained the catalyzed conversion of middle long chain alkane by glycerine of the present invention can prepare take middle long chain alkane (carbonatoms is as 6~24) as main oily matter.Among the present invention used carrier there is not special requirement, but the larger carrier of specific surface area, and effect is often relatively good.The present invention adopts equi-volume impregnating that metal is carried out load, and used metal has Ir, Rh, Re, W, Mo.The used mineral acid of the present invention can be sulfuric acid or phosphoric acid.Described mineral acid will have certain concentration, is preferably 5~50wt% and (is preferably 25~40wt%).The used hydrogen pressure of the present invention does not have the upper limit, but is preferably 4~15MPa, more preferably 6~10MPa.The used temperature of the present invention is 120~350 ℃, is preferably 150~250 ℃.Reaction times required for the present invention is preferably 48~72 hours.The present invention has also found such rule, and the concentration of acid is higher, the transformation efficiency of glycerine higher (within the identical time), and the middle long chain alkane that obtains is in the majority take the alkane of long-chain (carbonatoms is as 16~24).
The method that is obtained the catalyzed conversion of middle long chain alkane by glycerine of the present invention is: be that (aqueous solution that is preferably 25~40wt%) mineral acid obtains mixed solution to 5~50wt%, and wherein: the molar ratio of glycerine and mineral acid is 1~2 with glycerine and concentration; Then the catalyzer that in mixed solution, adds catalytic amount, (described stirring is to utilize magnetic stirring in stirring, the rotating speed of described magnetic stirring is generally about 1000rpm/min), be that 120~350 ℃ (being preferably 150~250 ℃) and the pressure of hydrogen (are preferably 4~15MPa in temperature, more preferably react (time of reaction is preferably 48~72 hours) under 6~10MPa), obtain carbonatoms and be 6~24 middle long chain alkane.
Described catalyzer is by the Primary Catalysts metal of load on carrier and help catalytic metal to form, and wherein the charge capacity of Primary Catalysts metal is 1~3wt% of vehicle weight; The quality ratio of the material of described Primary Catalysts metal and described promoter metal is 0.5~5.
Described Primary Catalysts metal can be Ir or Rh, and described promoter metal can be selected from a kind of among Re, W, the Mo or any two kinds.
