ABSTRACT:
A spent hydrotreating catalyst having carbonaceous and metallic deposits comprising generally cylindrical, free flowing particles of regular geometric shape having substantially the same diameter but of varying length is stripped, length graded, density graded using an upward flow of gas through an inclined, vibrating surface, and regenerated to achieve catalyst activity very near that of a fresh catalyst.
