ABSTRACT:
Improved aromatic conversion processes are provided by novel regeneration techniques. Aromatic processes that would benefit from this invention include those processes using catalysts comprising zeolites having a silica to alumina mole ratio of at least about 12 and a constraint index within the approximate range of 1 to 12 and which require regeneration to burn off coke from said catalysts. The improvement of the instant invention resides in conducting said regeneration in the presence of steam under controlled conditions to enhance the activity of the catalysts.
