ABSTRACT:
The conversion and/or selectivity of a zinc titanate catalyst, the conversion and/or selectivity of which has been reduced by use of the zinc titanate catalyst in a process in which the zinc titanate catalyst is exposed to reducing conditions such as those found in a dehydrogenation process, is improved by contacting the zinc titanate catalyst with a solution of zinc and then calcining the treated zinc titanate in the presence of free oxygen. This treatment improves the conversion and/or selectivity of the used zinc titanate catalyst.
