The catalyst is put in a reaction vessel at the reaction temperature of 180 to 200 DEG C and under the reaction pressure of 3.5 to 5MPa. The catalyst of the present invention has high activity, the conversion rate of furfural is more than 99.5%, and the selectivity of furfuralcohol is more than 97%.

Description

A kind of preparing furancarbinol from liquid-phase furol hydrogenation catalyzer and uses thereof
Affiliated field:
The invention belongs to a kind of catalyzer for preparing furfuryl alcohol and uses thereof, relate in particular to a kind of catalyzer that is used for preparing furancarbinol from liquid-phase furol hydrogenation and uses thereof.
Background technology:
Furfuryl alcohol is a kind of important organic chemical industry's intermediate, is mainly used in the fine chemistry industry aspect, can make levulinic acid (having another name called oxysuccinic acid), the furane resin of various performances (as furfuryl resin, furans I, II type resin), furfuryl alcohol-Precondensed UreaFormaldehyde Resin and resol etc.; Be widely used in building, the foundary industry, particularly automotive industry.
The at present industrial furfuryl alcohol of producing all is to adopt furfural shortening method to produce.China is furfural big producing country, and in the furfural deep processed product, furfuryl alcohol is to be worth very high a kind of product.
German patent DE 3,425,758 have reported CuO-Cr 2O 3And CuO/SiO 2Two portions catalyst mix is formed, and carries out preparing furancarbinol from liquid-phase furol hydrogenation, 150-300 ℃ of reaction conditions temperature, reaction pressure 2-10Mpa.Because of catalyzer is divided into two portions, increased the difficulty of preparation process.
Chinese patent ZL 91103132.4, the composition of " producing furfuryl alcohol thunder Buddhist nun's cobalt hydrogenation catalyst and method for making thereof " disclosed catalyzer: cobalt 35.1-46.5%, aluminium 40.2-60.7%, chromium 4.2-13.3%.Its activation method is used the distilled water cleaning catalyst then for to take out reactive aluminum with 20% caustic soda soln, and the pH value about 7 that makes scavenging solution is for extremely.120 ℃ of temperature of reaction, carry out preparing furancarbinol from liquid-phase furol hydrogenation under the condition of 1Mpa, transformation efficiency is greater than 99%.In this catalyst preparation process, need a large amount of cobalt metals, increased the expense of catalyzer; Thunder Buddhist nun cobalt catalyst belongs to the spontaneous combustion type in addition, need be kept in the ethanol, has increased the use difficulty.
Summary of the invention:
The object of the present invention is to provide that a kind of cost is low, preparation catalyzer of preparing furancarbinol from liquid-phase furol hydrogenation and uses thereof that is used for simple, easy to use.
Catalyzer each component weight percent of the present invention is:
CuO 50-53%?Cr 2O 3?47-50% Pt?0.08-0.15%
The weight percentage summation of each component is 100%.
Catalyzer of the present invention is to adopt precipitator method preparation, and concrete steps are as follows:
1. press the composition CuO 50-53% of catalyzer, Cr 2O 347-50%, Pt 0.08-0.15%, being mixed with concentration is the 1-2M metal salt solution;
2. with metal salt solution and alkaline precipitating agent, about 45 ℃ in temperature, mixing under stirring obtains precipitation, and churning time is 1 hour, aging 1-2 hour then;
3. throw out is through washing and filtering, 100-120 ℃ of drying 12 hours, and 300 ℃ of following roastings 5 hours, mills at last and promptly gets catalyzer.
As above-mentioned alkaline precipitating agent is ammoniacal liquor, yellow soda ash, volatile salt etc.
The reaction conditions of catalyzer of the present invention is temperature 180-200 ℃, pressure 3.5-5Mpa.
The present invention compared with prior art has following advantage:
Catalyst preparation process is simple, and higher activity and selectivity are arranged, and the furfural transformation efficiency is greater than 99.5%, and the selectivity of furfuryl alcohol is greater than 97%.
