Abstract:

In this paper, performance of two kinds of zeolites, HZSM-5 and SAPO-34 were compared.HZSM-5 and SAPO-34 zeolites were modified using cerum nitrate andlanthanum nitrate by impregnation. The effect of Ce and La on the structure and its catalytic performance for naphtha cracking reaction by XRD, SEM, BET were characterized and their performances to produce light olefins were investigated yield of propylene and ethylene by using modified HZSM-5 and modified SAPO- 34 were studied using a fixed bed reactor. Regarding the performance thermal catalytic cracking tests, SAPO-34 increased yield of ethylene.
