Abstract
The invention discloses the catalyst and preparation method thereof that a kind of furfural hydrogenation prepares furfuryl alcohol.The catalyst is using calcium carbonate as carrier, using copper oxide as active constituent;The weight of copper oxide is 32wt%~75wt% of total catalyst weight.The production cost of catalyst of the invention is significantly reduced, and furfural conversion ratio and hydrogenation selectivity are also relatively high.
Description
Technical field
The present invention relates to the catalyst and preparation method thereof that a kind of furfural hydrogenation prepares furfuryl alcohol.
Background technique
Furfuryl alcohol is a kind of important fine chemicals, is widely used in the industries such as synthetic fibers, rubber and pesticide.Furfuryl alcohol can
For manufacturing various kinds of resin, wherein the excellent plasticizer of cold tolerance can be made in furfuryl alcohol resin.In China, 80%~90% chaff
Alcohol is consumed in furane resins.Furane resins are widely used in foundary industry as binder.Furfuryl alcohol is the good molten of varnish, pigment etc.
Agent can also be used as rocket fuel.Levulic acid can be made through hydrolysis in furfuryl alcohol, be the intermediate of nutrient drug calcium levulinate.Chaff
Alcohol is also used to produce friction pulley thermostable phenolic resin binder, such as braking sheet for automobile etc..Furfuryl alcohol be also production fragrance,
Flavouring agent, medicine, pesticide intermediate.
Furfuryl alcohol is mainly derived from the deep processing of furfural, is that hydrogenation reaction occurs over just partial hydrogenation product on carbonyl.Chaff
Aldehyde hydrogenating catalyst includes SiO2The catalyst of load, TiO2-SiO2The catalyst of load, Al2O3The catalyst of load, class neatly
The catalyst etc. of stone load.From the catalyst for having Cr till now without Cr catalyst, developed to from imported catalyst domestic
The performance of catalyst, furfural catalyst is higher and higher.For technology, Technical furfural catalyst is with Cu/SiO2Based on, this is to urge
The advantages of agent is catalyst without Cr, but its selectivity has a certain gap compared with catalyst containing Cr.In addition, furfural hydrogenation
The production cost for preparing the catalyst of furfuryl alcohol is still relatively high.In order to the market competitiveness, it is also necessary to further reduce it
Production cost.
Currently, furfuraldehyde hydrogenation catalyst mostly uses greatly the oxide-based carrier such as silica or porous mass class carrier.
For example, patent document CN102247883A is using loaded copper oxide on silica gel-modenite complex carrier;CN103007941A is adopted
With copper oxide-silica composite oxides;Nano-metallic copper dispersion is anchored to shape on magnesia matrix by CN104841436A
At catalyst;The carrier of CN105148923A is carbon nanotube, carbon fiber, graphene, SBA-15, gama-alumina or titanium dioxide
Titanium;JP Tetsukai 2015-229657A is using transition metal such as mesoporous silicon oxide solid supported nickel, palladium, gold, copper, ruthenium and rhodiums;
US4185022A is used and is deposited with copper-sodium metasilicate float stone as catalyst;It includes copper and fumed silica that US5591873A, which is used,
Catalyst;US5977010A uses the catalyst including copper oxide, clay and the calcium silicates being formed in situ.For another example, non-patent
Document 1 (Li Guoan, Speciality Petrochemicals, the 1st phase, the 40-44 pages, nineteen ninety-five) discloses several preparing furancarbinol from liquid-phase furol hydrogenation
Catalyst, active constituent Cu, carrier are selected from γ-A12O3, active carbon, TM grades of white carbon blacks, general purpose grade SiO2、SiO2(40-120
Mesh) or SiO2(110-120 mesh).
The existing reduction for being mainly used for unsaturated carbon carbon bond using calcium carbonate as the catalyst of carrier, and grain is mostly used greatly
Spend biggish calcium carbonate.For example, CN101811042A discloses one kind using palladium as active component, calcium carbonate or barium sulfate are carrier
Selective hydrocatalyst.The catalyst is used to 1,4- butynediols being reduced to 1,4- butylene glycol.That is, this is urged
Reduction reaction of the agent for triple carbon-carbon bonds to carbon-carbon double bond.For another example, CN104394988A discloses a kind of part hydrogenated carbon carbon
The pull-up catalyst of woods moral of three keys, support material be partial size be greater than 10 μm, the calcium carbonate less than 120 μm, active constituent be Pd and
Pb.The catalyst is also the reduction reaction for triple carbon-carbon bonds to carbon-carbon double bond.The patent document also indicates that: when for calcium carbonate
When the partial size of support material is greater than 10 μm, the selectivity of hydrogenation process is significantly improved.It can be seen that it is existing with calcium carbonate be carry
The catalyst of body is not used to the reduction of carbon oxygen unsaturated bond (such as carbonyl).In addition, such existing catalyst requirement carbon
The granularity of sour calcium has to be larger than 10 μm.
To sum up, in the catalyst that existing furfural hydrogenation prepares furfuryl alcohol, there is no be using calcium carbonate as carrier, with copper
The catalyst of active constituent;Particular without using calcium carbonate superfine powder as carrier, using copper as the catalyst of active constituent.In furfural
Hydrogen is added to prepare in the industrialized production of furfuryl alcohol, catalyst occupies its very big cost.If can be made with cheap calcium carbonate
Palladium isoreactivity ingredient is replaced by carrier and with relatively inexpensive copper activity ingredient, then for reducing the production cost of furfuryl alcohol very
It is important, it is also most important for improving the furfuryl alcohol competitiveness of product in market.
