REGENERATION OF CATALYST USED IN PURIFICATION OF AROMATIC STREAMS

The invention relates to regeneration of catalysts used in the purification of aromatics streams. It has been surprisingly found that retaining small amount of coke on the catalyst reduces regeneration costs and improves regeneration effectiveness. La présente invention concerne la régénération de c...

Zusammenfassung:	The invention relates to regeneration of catalysts used in the purification of aromatics streams. It has been surprisingly found that retaining small amount of coke on the catalyst reduces regeneration costs and improves regeneration effectiveness. La présente invention concerne la régénération de catalyseurs utilisés lors de la purification de flux aromatiques. On a découvert que la rétention d'une petite quantité de coke sur le catalyseur permettait de réduire les coûts de régénération et améliorer l'efficacité de la régénération.
