VERFAHREN ZUR REGENERIERUNG EINES ZUMINDEST TEILWEISE DESAKTIVIERTEN KATALYSATORS ZUR UMWANDLUNG VON KOHLENWASSERSTOFFEN

摘要

Process for regenerating hydrocarbon conversion catalysts, particularly for reforming and isomerization, which comprises superhalogenating the deactivated catalysts, burning the accumulated coke in a controlled manner preferably in a series of steps at different temperatures and oxygen percentages with an oxygen containing gas stream; treating the combusted catalyst with a further gas stream containing oxygen and a halogen (preferably chlorine), and thereafter reducing the catalyst with hydrogen in the practical absence of oxygen.
