Claim 1
Independent Claim
212 words
A REACTOR FOR A LIQUID-SOLIDS-GASEOUS REACTION WHEREIN THE LIQUID AND GAS IN CONTINUOUS PHASE PASS UPWARDLY THROUGH THE SOLIDS TO CAUSE AN EXPANSION OF THE SOLIDS OF AT LEAST 10% BASED ON THE SETTLED VOLUME THEREOF, AND WHEREIN THE SOLIDS ARE MAINTAINED IN RANDOM MOTION IN THE LIQUID WITHOUT SUBSTANTIAL CARRYOVER FROM THE REACTOR WHICH COMPRISES A SUBSTANTIALLY VERTICAL VESSEL ADAPTED TO CONTAIN SAID SOLIDS, A PERFORATED PLATE IN SAID VESSEL BELOW SAID SOLIDS, MEANS TO FEED GAS AND LIQUID BELOW SAID PERFORATED PLATE AND THROUGH THE PERFORATIONS IN SAID PLATE AT A VELOCITY TO MAINTAIN SAID SOLIDS IN RANDOM MOTION IN THE LIQUID, COVERING ELEMENTS SUPERPOSED OVER ALL OF SAID PERFORATIONS IN SAID PLATE, SAID COVERING ELEMENTS HAVING A HORIZONTAL COMPONENT AS COMPARED TO THEIR HORIZONTAL SPACING ON THE PERFORATED PLATE SUCH AS TO MAINTAIN AN UNFAVORABLE ANGLE OF REPOSE OF THE SOLIDS THAT WILL PREVENT THE SOLIDS FROM FLOWING DOWNWARDLY THROUGH THE PERFORATED PLATE, SAID COVERING ELEMENTS BEING ADAPTED TO SUBSTANTIALLY UNIFORMLY DISTRIBUTE THE LIQUIDGAS MIXTURE ACROSS THE HORIZONTAL CROSS-SECTION OF THE REACTOR, SAID REACTOR HAVING A SUPPLEMENTARY GAS DISTRIBUTOR MOUNTED ABOVE THE COVERING ELEMENTS IN THE LOWER PART OF THE REACTOR, SAID SUPPLEMENTARY GAS DISTRIBUTOR BEING INTERCONNECTED TO GAS INLET MEANS FOR UPWARD FLOW OF GAS THROUGH THE LIQUID.
