Abstract
The present invention relates to a catalyst having an amorphous support and one or more active metals. The amorphous support may comprise a support material and an amorphous support modifier, which adjusts the acidity of the support material. In preparing the amorphous catalyst, post-synthesis treatment, i.e. calcination, may be used to adjust the catalyst performance while converting acetic acid to ethanol.
