Description:

The FCC unit has traditionally been the major gasoline producer in refinery operations. In recent years the operating objectives for FCCU’s have become increasingly complex as refiners have adapted to the changing demands of the marketplace. These factors include octane demand due to lead phaseout, increased use of “opportunity feeds” such as purchased gas oils and resid, implementation of reformulated gasoline production, and integration with petrochemical operations as a feedstock producer. FCC process technology advances, such as improved feed distribution and installation of advanced riser termination designs, have been incorporated into a growing number of units, These changes have had a marked impact on FCC unit operations. One of the key variables in addressing these continually changing needs is the catalyst. Customization of fresh catalyst properties to address specific unit needs has become standard practice. The interaction of the fresh catalyst properties, catalyst management policy, feedstock and operating variables ultimately dictate the properties of the equilibrium catalyst inventory. Engelhard maintains an extensive data base of equilibrium FCC catalyst properties for operating units worldwide compiled from our ongoing equilibrium catalyst analysis service. An analysis of some of the trends in activity and selectivity related parameters through the first half of the 1990’s offers insight into how refiners have adapted this key part of their FCCU operation to meet their ever changing demands.
