A METHOD FOR REACTING A FLUID IN CONTACT WITH A MASS OF SUBDIVIDED SOLID PARTICLES WHICH COMPRISES MAINTAINING A CONTINUOUS COMPACT BED OF SAID SOLID PARTICLES UNDER REACTION CONDITIONS WITHIN A CONFINED REACTION ZONE FROM ADJACENT ITS UPPER EXTREMITY TO ITS LOWER EXTREMITY, CAUSING THE PARTICLES OF SAID BED TO MOVE DOWNWARDLY THROUGH THE REACTION ZONE BY CONTINUOUSLY SUPPLYING PARTICLES TO THE UPPER PORTION OF THE BED AND CONTINUOUSLY REMOVING PARTICLES FROM THE LOWER PORTION OF THE BED, SUPPLYING A STREAM OF SAID FLUID TO THE UPPER PORTION OF THE REACTION ZONE AND REACTING THE FLUID WHILE PASSING DOWNWARDLY THROUGH AN UPPER PORTION OF SAID BED, REVERSING THE DIRECTION OF FLOW OF SAID FLUID IN A HORIZONTALLY ENLARGED POWER PORTION OF SAID BED AND DISCHARGING FLUID FROM THE ENLARGED PORTION OF SAID BED AT A PLURALITY OF SPACED APART DISENGAGING SURFACES PROVIDING A GREATER TOTAL AREA FOR GAS FLOW THAN THE PROTION OF SAID BED WHICH IS ABOVE SAID ENLARGED LOWER PORTION.
