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.

Abstract: Provided are catalysts suitable for the production of tetrahydrofuran from 1,4-butanediol. Also provided are methods of use of these catalyst, as well as catalyst systems. The catalysts described herein contain only Lewis acidity, but not Brønsted acidity, which results in decreased production of ether byproducts.
