Abstract
The catalytic conversion of isopropanol on pure chromia, pure alumina and chromia-alumina mixtures at 280 °C was studied. The effects of catalyst composition and calcination temperature on the activity and selectivity of the catalysts were investigated using a micropulse technique. The activity and selectivity of the pure alumina catalyst were found to be almost unaffected by calcination. Pure chromia calcined at 600 °C acted mainly as a dehydrogenating catalyst whereas chromia pretreated at 400 °C possessed both dehydrogenating and dehydrating properties. The activity and selectivity of the mixed oxide catalysts were found to be dependent on both catalyst composition and calcination temperature.
