Abstract
A catalyst for preparing furfuryl alcohol by hydrogenating liquid-phase furaldehyde contains CuO, Cr2O3 and Pd. Its advantages are high activity, conversion rate and selectivity.
Description
Technical field
The invention belongs to catalyzer 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.
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
