Abstract
The operation of fluid catalytic converter (FCC) units can be stabilized through use of tests wherein a first catalyst and a second catalyst are introduced into the FCC unit in at least two different ratios, at two different times, in order to establish the effect of these catalyst ratios on a given operating parameter. This information is used to establish a unit response curve (or unit response envelope) for the catalyst ratios versus the operating parameter. This unit response curve (or envelope) is thereafter used to control the operation of the FCC unit.
