REGENERATION OF AROMATIC ALKYLATION CATALYSTS USING HYDROGEN-CONTAINING GASES

Title:

REGENERATION OF AROMATIC ALKYLATION CATALYSTS USING HYDROGEN-CONTAINING GASES

Document Type and Number:

WIPO Patent Application WO/2014/182440

Kind Code:

A8

Abstract:

The present invention provides a process for regenerating a spent catalyst comprising a molecular sieve, the process comprising the step of contacting the spent catalyst with a hydrogen-containing gas under catalyst reactivation conditions. The regenerated catalyst formed is preferably used in aromatic alkylation and transalkylation processes.
