Abstract:
1. A process for producing ethanol comprising: contacting a feed stream comprising acetic acid and hydrogen in a reactor at an elevated temperature with a hydrogenation catalyst comprising an amorphous support and one or more active metals, wherein the hydrogenation catalyst is prepared by: contacting a precursor to an amorphous support modifier with a support material to form a catalyst solution, wherein the support modifier is selected from the group consisting of (i) alkaline earth metal oxides, (ii) alkali metal oxides, (iii) alkaline earth metal silicates, (iv) alkali metal silicates, (v) Group IIB metal oxides, (vi) Group IIB metal silicates, (vii) Group IIIB metal oxides, (viii) Group IIIB metal silicates, and mixtures thereof; calcining the catalyst solution at a temperature from 400° C. to 750° C. to decompose the precursor to form the amorphous support; and adding the one or more active metals to the amorphous support.
