Multi-zone catalytic cracking of crude oils

Multi-zone catalytic cracking of crude oils

A method of processing a hydrocarbon feed may comprise fractionating the hydrocarbon feed into a light stream, a middle stream and a heavy stream; hydrotreating the heavy stream to form a hydrotreated heavy stream; feeding the light stream to a first Fluid Catalytic Cracking (FCC) reaction zone; fee...

Zusammenfassung:A method of processing a hydrocarbon feed may comprise fractionating the hydrocarbon feed into a light stream, a middle stream and a heavy stream; hydrotreating the heavy stream to form a hydrotreated heavy stream; feeding the light stream to a first Fluid Catalytic Cracking (FCC) reaction zone; feeding the middle stream to a second FCC reaction zone; and feeding the hydrotreated heavy stream to a third Fluid Catalytic Cracking (FCC) reaction zone. The light stream may comprise hydrocarbons boiling at less than 200° C. The middle stream may comprise hydrocarbons boiling at from 200° C. to 370° C. The heavy stream may comprise hydrocarbons boiling at greater than greater than 370° C. Each of the first and second FCC reaction zones may operate under more severe operating conditions than the third FCC reaction zone.
