ABSTRACT:
A spent butane isomerization catalyst comprising platinum and chlorine or alumina is converted in an active n-pentane isomerization catalyst by a process comprising calcining and subsequent heating with a fluorocarbon and/or chlorofluorocarbon. The thus prepared catalyst can be used in the isomerization of n-pentane to isopentane.
