ABSTRACT:
A resid refining reactor has an ebullated catalyst bed. Hydrogen gas is released into the catalyst bed at a point which is far enough above a distributor plate at the bottom of the catalyst bed to form a gas updraft in a committed zone through the bed. This committed updraft causes a reduction in gas holdup which increases the residence time of a liquid phase in the catalyst bed.
