This patent describes a fluid catalytic cracking unit. It comprises: a catalyst regenerator vessel; a catalyst reactor vessel positioned directly over the catalyst regenerator vessel; means for communicating spent catalyst from the reactor vessel to the regenerator vessel; a mixing chamber for mixing catalyst and oil feedstock. The mixing chamber being positioned beneath the lowermost level of the catalyst regenerator vessel; a first conduit disposed between the mixing chamber and a lower portion of the regenerator vessel; means for regulating flow of catalyst in the conduit from the regenerator to the mixing chamber; means for injecting an oil feedstock into the mixing chamber; a riser reactor having a first end in fluid communication with the mixing chamber and a second end in fluid communication with the reactor vessel; a first catalyst well mounted on a lower interior portion of the regenerator vessel. Wherein one end of the conduit is in fluid communication with the first catalyst well; a second catalyst well mounted on a lower interior portion of the catalyst regenerator vessel; and a second conduit disposed between the second catalyst well and the mixing chamber.
