Abstract
A catalytic cracking system in which liquid hydrocarbon and bio-oil are directed into a reactor riser of a fluid catalytic cracking unit by separate feed spray nozzle assemblies. To protect liquid bio-oil directed through the liquid bio-oil feed nozzle assembly from high temperature degradation, an insulating layer is provided between a central bio-oil feed tube in a concentrically surrounding atomizing gas passageway. Cooling channels also may be provided in the spray tip of the bio-oil feed nozzle assembly.
