ABSTRACT:
A process for converting catalytic cracking catalyst fines to a shaped composition comprises acid-treatment of catalytic cracking catalyst fines, followed by separation and drying of the acid-treated fines; preparing a shapable mixture by mixing the dried catalyst fines with calcium aluminate, sodium silicate, phosphoric acid and water; shaping (preferably extruding) the obtained shapable mixture; and drying and thereafter calcining the obtained shaped particles. A shaped composition having high crash strength is obtained by this process.
