Abstract
A METHOD FOR REGENERATING A USED FLUORINATION CATALYST SUCH AS A CHROMIUM-CONTAINING COMPOUND COMPRISES CONTACTING THE USED CATALYST AT A TEMPERATURE OF 300?C TO 500?C WITH A MIXTURE OF AN OXIDISING AGENT, ESPECIALLY AIR, AND HYDROGEN FLUORIDE AND OPTIONALLY AND INERT DILUENT SUCH AS NITROGEN, SAID MIXTURE CONTAINING UP TO 30OF OXIDISING AGENT ON A MOLAR BASIS. THE METHOD OBVIATES CHROMIUM LOSS DURING REGENERATION/REFLUORINATION OF SPENT CATALYST AND PROVIDES HEATED HYDROGEN FLUORIDE FOR USE DIRECTLY IN FLUORINATION REACTIONS.
