摘要

A chromia-based fluorination catalyst comprising at least one additional metal selected from zinc, nickel, aluminium and magnesium in which from 0.1 to 8.0 % by weight of the catalyst is in the form of one or more crystalline compounds of chromium and/or one or more crystalline compounds of the at least one additional metal.
