 Abstract
Study of ZSM-5 addition on the performance of a catalytic cracking catalyst industry was achieved by determining the conversion and products yield obtained in the cracking of industrial feed. Yields of products linearly vary with increasing of the amount of ZSM-5 added. Addition of ZSM-5 significantly increases the yield of propylene, gasoline and diesel octane number, but keeps the coke level approximately constant. The study was performed using the ASPEN-HYSYS program, using a model witch reflect a real fluid catalytic cracking plant.

 Rezumat
Studiul adaosului de ZSM-5 asupra performanţelor unui catalizator industrial de cracare catalitică a fost realizat prin determinarea conversiei şi a randamentelor produselor de reacţie obţinute la cracarea unei materii prime industriale. Randamentele de produse variază liniar la creşterea cantităţii de ZSM-5 adăugate.
Adaosul de ZSM-5 creşte semnificativ randamentul de propenă, cifra octanică a benzinei şi a motorinei şi menţine cocsul la nivel constant. Studiul a fost efectuat cu ajutorul programului ASPEN-HYSYS, utilizând un model care să reflecte cât mai fidel o instalaţie industrială de cracare catalitică.
