A METHOD OF RACING A GASOUS REACTANT WITH COMMINUTED SOLIDS, COMPRISING THE STEPS OF: INTRODUCING ON UPWARD FLOW OF SAID GASEOUS REACTANT INTO THE LOWER END OF AN INCLINED, ELONGATED REACTION ZONE; INTRODUCING A FLOW OF SAID COMMINUTED SOLIDS INTO THE UPPER END OF SAID REACTION ZONE; IMPOSING AN ALTERNATING ELECTROSTATIC FIELD IN SAID REACTION ZONE HAVING A FREQUENCY AND VOLTAGE INTENSITY SUFFICIENT TO VIOLENTLY AGITATE THE SAID PARTICLES AND CAUSE THE SAME TO FLOW DOWNWARDLY THROUGH THE ZONE PRODUCING THE APPEAREANCE OF A HOMOGENOUS SUSPENSION IN THE REACTANT GAS AND TO FLWO DOWNWARDLY THROUGH THE INCLINED ELONGATED ZONE AGAINST THE UPWARD FLOW OF THE GAS; COLLECTING GASES FLOWING THROUGH AND FORMED WITHIN THE REACTION ZONE AT THE UPPER END OF THE REACTION ZONE AS THEY FLOW UPWARDLY THROUGH THE ZONE, THEREBY PRODUCTING COUNTERFLOW OF GAS AND PARTICLES THROUGH THE LONGITUDINAL EXTENT OF THE REACTION ZONE TO ENHANCE A SUBSTANTIALLY COMPLETE REACTION WITH A
