ABSTRACT:
The method for preparing furfuryl alcohol comprises hydrogenation of furfural in the presence of a mixture of a copper-chromite catalyst promoted with oxides of alkali-earth metals, and ceramic material. This mixture is disposed in four beds at a ratio between the catalyst and the ceramic material of 1:2 in the first bed, 1:1 in the second bed, 2:1 in the third bed and 2.5:1 in the fourth bed downstream of the flow of the mixture of furfural and hydrogen. The hydrogenation process is conducted at an elevation of temperature from 50.degree. to 140.degree. C. under a pressure of from 60 to 65 atm, followed by the introduction of monoethanolamine or hydrazine hydrate into the resulting catalyzate.
