Catalytic Selectivity of Uranium Oxide Catalyst for Dehydrogenation and Dehydration of Ethanol

Abstract

The catalytic selectivity of the three uranium oxides, UO3, Us08 and UO2, for dehydrogenation and dehydration of ethanol was investigated using the pulse-reaction method.As is shown in Fig.1, the catalytic activities varied initially as the injection of reactant was repeated, and then reached nearly stationary values. During the course of reaction, the uranium oxides except UO2 were reduced to oxides of uranium of lower oxidation states. An interesting relationship was found between the oxidation state of uranium and the catalytic selectivity, as is summarized in Table 1.
