Title: REGENERATION METHOD FOR PLATINUM-CONTAINING ISOMERIZATION CATALYST
Abstract:
The invention is directed to a process for rejuvenating a devitalized alkane isomerization catalyst, which comprises platinum (Pt) and chlorine on an alumina support and is used in the production of MTBE, by removal of deposited carbonaceous and sulfurous material. The spent catalyst is rejuvenated by treating it with alcoholic solutions containing, e.g., an alkali metal hydroxide and then treating it with a chlorine-containing compound such as chloroform.
