Catalyst deactivation and the effect of catalyst makeup on the FCC unit
نویسندگان
چکیده
One of the significant processes crude oil refining process is fluid catalytic cracking (FCC) unit. This unit produces olefins and other feedstock for petrochemical industry as well high octane gasoline, naphtha, light cycle oil, heavy oil. Attrition one forms catalyst deactivation on FCC which affects its operation, thereby giving rise to a amount makeup compensate losses in this study investigated effect attrition commercial through an analysis technical data from 4-run operations. The loss profile was evaluated while scanning electron microscopy (SEM) showed abrasion dominant type unit, hence resulting many particles being lost micro fines elutriation. A simulation carried out using ASPEN HYSYS version 8.8 assess effects reduction increment fresh product yield cost done evaluate economic implication. results that 2% current daily gave same reference value. products also had similar qualities showing $117,000.00/annum could be saved by makeup.

The fundamentals of catalyst deactivation are presented in this review. The chemico-physical aspects concerning the various deactivation causes (i.e. poisoning, sintering, coking, solid-state transformation, masking, etc.) have been analyzed and discussed, along with the mathematical description of the deactivation phenomena. # 1999 Elsevier Science B.V.
