Description
Technical Field
The invention relates to the field of chemical agents, in particular to a double-transition metal hierarchical pore catalyst and a preparation method and application thereof.
Background
At present, furfuryl alcohol is industrially prepared by a furfural catalytic hydrogenation method. China is a large country for producing furfural, and in the subsequent products of furfural deep processing, furfuryl alcohol is one of products with high value, and the chemical name of furfuryl alcohol is 2-hydroxymethyl furan, and the furfuryl alcohol is an important intermediate of spice, flavoring agent, medicine, pesticide and solvent. The furfuryl alcohol can be used for producing levulinic acid, furfural resin, furan resin, modified urea-formaldehyde, phenolic resin and the like, wherein 80-90% of the furfuryl alcohol is consumed in the production of the furan resin.
At present, the industrial preparation of furfuryl alcohol by catalytic hydrogenation of furfural mainly comprises two processes of high-pressure liquid-phase hydrogenation and low-pressure gas-phase hydrogenation, which have respective advantages and disadvantages (such as Chinese patents CN 1876233A, CN 106807423A, CN 106749120A, CN 109776628A and the like), and particularly, the high-pressure liquid-phase hydrogenation method has high requirements on equipment, so that the equipment investment cost is directly increased; the low-pressure gas-phase hydrogenation method has higher requirements on the catalytic activity of the catalyst. At the same time, a common disadvantage of hydrogenation, whether in gas phase or liquid phase, is the large amount of industrial H required2As a source of hydrogen. Meanwhile, dehydrogenation reaction of cyclohexanol, cyclopentanol and other cyclic alcohols is industrially required to be carried out in a fixed bed (such as chinese patents CN 103285848B, CN 103861626A, CN 105218342A and the like) after high-temperature vaporization due to high activation energy and reversibility, side reaction is easily generated, and H is removed2Cannot be utilized. Both of the above processes result in higher energy consumption and equipment costs.
