Abstract
The invention belongs to polyalcohol catalyst field, and in particular to a kind of catalytic cellulose converts polynary alcohol catalyst and preparation method thereof and application method.The present invention is using carbon carrier as catalyst carrier, using two-step method first in its area load heteropoly acid, supported active metals component on this basis again, two kinds of functions of catalyzing hydrolysis and catalytic hydrogenation are concentrated on into a kind of catalyst, the hydrolysis of cellulose and hydrogenation are concentrated on into primary first-order equation process during use, cellulose has been simplified to the step of converting of polyalcohol, has improved transformation efficiency.The specific surface area of catalyst of catalytic cellulose conversion polyalcohol of the present invention is big, and heat endurance is good, and loss of active component is few, and cellulose high conversion rate, catalyst is easily separated with reaction product, can be recycled, and is a kind of green catalyst of good performance.The preparation process and use process of the polynary alcohol catalyst of catalytic cellulose conversion of the present invention are simple, and non-environmental-pollution is low for equipment requirements.
Description
Technical field
The invention belongs to catalytic cellulose to convert polyalcohol catalyst field, and in particular to a kind of catalytic cellulose conversion is more
First alcohol catalyst and preparation method thereof and application method.
Background technology
As the increasingly reduction of fossil resources and environmental problem constantly deteriorate, biomass resource is because of its recyclability, dioxy
Changing the good environment effects such as carbon zero-emission becomes the focus of global concern.Cellulose is widely present in agriculture as non-cereal crops
Woods discarded object, such as maize straw, bagasse and discarded sawdust, are biomass resources most abundant on the earth, annual output
More than 100,000,000,000 tons.Cellulose is a kind of straight-chain polysaccharide macromolecule formed by β-D-Glucose by β -1,4- glucosides key connections
Compound.By chemical catalysis means, cellulose through hydrolyze hydrogenation coupled reaction can be converted into polyalcohol, as sorbierite, glycerine,
Ethylene glycol and propane diols etc., these polyalcohols be considered as a new generation greening platform compound, available for production bio-fuel-oil,
Chemicals etc..
The reaction process of cellulose conversion polyalcohol includes:(1) hydrolysis of cellulose;(2) hydrolysate is hydrogenated to more
First alcohol.Method for transformation main at present is that, first with inorganic acid such as hydrochloric acid, sulfuric acid, phosphoric acid, heteropoly acid, hydrolyzes cellulose
It is then rapid Hydrogenation under Ru, Ni isoreactivity metallic catalyst catalytic action in carrying active component into monose and oligosaccharide
Obtain polyalcohol.There is the problem of acid separation and recovery in this method, in addition, reaction temperature is higher, acid under the high temperature conditions, to anti-
Answer the requirement of equipment very high.
The content of the invention
To solve above-mentioned the deficiencies in the prior art, the present invention provides a kind of catalytic cellulose convert polynary alcohol catalyst and
Its preparation method and application method.
Technical solution of the present invention:
It is carried heteropoly acid and activity at the same time on the carbon carrier that a kind of catalytic cellulose of the present invention, which converts polynary alcohol catalyst,
Metal salt is made, and the carbon carrier is carbon nanotubes, and the heteropoly acid is H4SiW12O40、H3PW12O40One or both of
Mixture, the active metal salt are RuCl3Or Ni (NO3)2·6H2One or both of O.
The preparation method step that a kind of catalytic cellulose of the present invention converts polynary alcohol catalyst is as follows:
Step 1:Heteropoly acid saturated solution is prepared, carbon carrier is added in heteropoly acid saturated solution, at a certain temperature
Ultrasonic immersing is carried out, carbon carrier taking-up drains away the water after completing ultrasonic immersing, is dried in vacuo, the carbon that carried heteropoly acid is made carries
Body;
Step 2:Active metal salt is configured to the stablizing solution of certain mass concentration;
Step 3:The carbon carrier for the carried heteropoly acid that step 1 is obtained adds active metal salt solution made from step 2
In, ultrasonic immersing at a certain temperature, the collected by suction carbon carrier of carried heteropoly acid and active metal salt at the same time after dipping,
It is dried in vacuo after the carbon carrier is washed with deionized, the carbon carrier is carried out at a certain temperature using reducing gas
Reduction treatment, completes reduction treatment postcooling to room temperature, obtains catalytic cellulose and convert polynary alcohol catalyst.
Further, heteropoly acid described in step 1 is H4SiW12O40、H3PW12O40One or both of mixture;Institute
It is carbon nanotubes to state carbon carrier;The ultrasonic immersing is ultrasonic immersing 20-180min at 60-120 DEG C;The vacuum drying is
50-120 DEG C of vacuum drying 12h.
Further, the carbon nanotubes is short hydroxyl multi-walled carbon nano-tube or short functionalized multi-wall carbonnanotubes, its
