Catalyst for dehydrogenation of cyclohexanol and method for preparation thereof
First Claim
1. A catalyst for dehydrogenation of cyclohexanol, said catalyst being a copper oxide based catalyst which includes essential components of copper oxide and a noble metal, wherein said catalyst contains 20 to 400 ppm of at least any one element selected from Pd, Pt and Ru as a component of said noble metal, and an oxide of at least one metal selected from Al, Zn and Si as an additive component.

Abstract
A copper oxide based catalyst for dehydrogenation of cyclohexanol, which is a copper oxide-zinc oxide based catalyst or a copper oxide-silicon oxide based catalyst further comprising one of palladium, platinum and ruthenium in a very small amount; and a method for preparing the copper oxide based catalyst which comprises combining the co-precipitation method or the kneading method and the spray method. The copper oxide based catalyst for dehydrogenation of cyclohexanol exhibits high activity and high selectivity, and thus may be used for producing cyclohexanone at a reduced reaction temperature and/or with an enhanced yield, as compared to a conventional catalyst.
