The Effect of Calcination Temperature on the Activity and Certain Physicochemical Properties of Water-Gas Shift Reaction Catalysts (original) (raw)

Afinidad, 2002

Abstract

e effect of calcination temperature on the activity and some properties of low temperature water gas shift reaction catalysts has been studied. It has been found that the catalysts' surface area decreased with increase incalcination temperature. The presence of an amorphous CuO phase within the structure of some catalysts has been related to the desirable conditions prevailed during the synthesis of the latter. The copper crystallite particle size has been observed to increase with temperature. The activities of catalysts have been determined using a fixed bed catalytic reactor. It has been observed that the catalyst's activities were normally enhanced with increase in temperature and pressure of the reaction systems.
