METHOD OF CIRCULATION GAS DRYING IN PROCESS OF CATALYTIC REFORMING Russian patent published in 2009 - IPC B01D53/28 B01J20/34 

FIELD: technological processes.

SUBSTANCE: invention concerns gas drying and method circulation gas drying In the process of catalytic reforming involving gas contact to solid sorbent and sorbent recovery in heated gas flow, where drying of hydrogen-containing reforming gas or of reforming catalyst recovery gas is performed with solid sorbent containing porous matrix with bulk specific gravity not less than 0.65 g/cm³, total pore volume not less than 0.55 cm³/g, average pore diametre of 7-12 nm. Aluminium oxide, silicoaluminate or carbon material is used as a porous matrix and coated with anhydrous calcium chloride in amount of up to 20 wt % of the total sorbent contents. Sorbent regeneration is performed at 80-150°C.

EFFECT: enhanced efficiency of circulation gas drying in the process of catalytic reforming both at reforming catalyst launching and operation stages and on catalyst recovery stages.
