A model on the performance of riser section in a fluid catalytic reactor

Refiners are under pressure to increase their product slates and specifications in response to market forces, changing crude supplies and environmental regulations. The latter eventually requires the refiners to reformulate their gasoline, and currently pressures are mounting to reformulate diesel fuels as well. The Fluid Catalytic Cracker (FCC) is a ley process in a refinery that can be used to alter product slates and increased yields.
