Abstract
A catalyst comprising a first metal, a silicaceous support, and at least one metasilicate support modifier, wherein at least 1 wt. % of the at least one metasilicate support modifier is crystalline in phase, as determined by x-ray diffraction. The invention also relates to processes for forming such catalysts, to supports used therein, and to processes for hydrogenating acetic acid in the presence of such catalysts.
Claims9
A process for producing ethanol, comprising hydrogenating acetic acid in the presence of a catalyst comprising a first metal, a silicaceous support, and at least one metasilicate support modifier, wherein at least 0.5 wt. % of the metasilicate support modifier is in a crystalline phase, as determined by XRD.
