Abstract
Catalysts and methods for their manufacture and use for the dehydrogenation of alcohols are disclosed. The catalysts and methods utilize a highly dispersible alumina, for example, boehmite or pseudoboehmite, to form catalysts that exhibit high dehydrogenation activities. Specifically, the catalysts include Cu that is highly dispersed by reaction of an alumina formed by peptizing of boehmite or pseudoboehmite and precursors of ZrO2, ZnO and CuO.

1-7. (canceled)
A dehydrogenation catalyst comprising about 10 to about 75 weight % CuO, about 5 to about 50 weight % ZnO, about 1 to about 30 weight % ZrO2, and about 5 to about 40 weight % alumina prepared by peptizing dispersible alumina with a dispersibility of at least about 50% or greater and reacting the alumina with precursors of CuO, ZnO, and ZrO2, wherein the nondispersible alumina is selected from γ-alumina, η-alumina, χ-alumina, other transitional aluminas, boehmite, pseudoboehmite, gibbsite, bayerite, and mixtures thereof.
A method for dehydrogenating an alcohol comprising contacting an alcohol-containing stream with a catalyst of claim 1, which has been reduced in a stream containing hydrogen, and converting the alcohol to an ester.
