Abstract
A startup method for a fluidized catalytic cracking (FCC) unit operating with a magnetic catalyst separation means is disclosed. Magnetic strength, or separation severity, is maintained or increased until most of the catalyst has passed through the magnetic separation unit. After this point, magnetic flux and/or centrifugal forces, are decreased for lined-out operation. Preferably a MagnaCat.RTM. catalyst separation unit is used for magnetic fractionation of catalyst.
