Abstract:
The presence of nitrogenous compounds in the braziiian gasoil reduces
the performance of the zeolite based catalyst used in the fluid catalytic cracking
(FCC) process. The FCC is the main process of the oil refining, which converts heavy
feedstocks into light more valuable hidrocarbons, specially gasoline and light olefins.
The n-heptane cracking was used as a model reaction either pure or in the presence
of 1 % quinoline (C9H7N), aiming to study the quinoline influence on the H-Y zeolite
deactivation. The obtained results confirm the poisoning effect of quinoline during nheptane
cracking over a commercial Y zeolite (CBV 500). Indeed, the activity of this
catalyst is severely reduced in the presence of this base. The deactivation of the HY
zeolite is mainly related to coke formation, being more pronounced when quinoline is
present in the feed.
