Claim 1
Independent Claim
174 words
THE METHOD OF SEPARATING PARTICLES OF SOLID OXIDE CATALYSTS AND SOLID OXIDE CATALYST CARRIES FROM ADMIXTURE WITH PARTICLES OF AN ION EXCHANGE RESIN IN AN AQUEOUS MEDIUM, INCLUDING SOLID OXIDE PARTICLES HAVING THE SAME ELUTRIATION CHARACTERISTICS AS SAID RESIN PARTICLES, SAID SOLID OXIDE PARTICLES RANGING IN DIAMETER FROM ABOUT 20 MICRONS TO ABOUT 300 MICRONS AND SAID RESIN PARTICLES RANGING IN DIAMETER FROM ABOUT 0.4 MILLIMETER TO 2.0 MILLIMETERS, WHICH COMPRISES CONTACTING SAID MIXTURE OF SOLID OXIDE PARTICLES AND RESIN PARTICLES WITH AN ASCENDING AQUEOUS STREAM HAVING A SUPERFICIAL VELOCITY RANGING FROM ABOUT TWO FEET PER MINUTE TO ABOUT EIGHT FEET PER MINUTE TO SEPARATE A MAJOR PORTION OF SAID SOLID OXIDE PARTICLES FROM SAID RESIN PARTICLES AND THEREAFTER SEPARATING SAID RESIN PARTICLES FROM THE REMAINING SOLID OXIDE PARTICLES, INCLUDING SAID SOLID OXIDE PARTICLES HAVING THE SAME ELUTRIATION CHARACTERISTICS AS SAID RESIN PARTICLES, BY PASSING THE MIXTURE OF REMAINING SOLID OXIDE PARTICLES AND RESIN PARTICLES OVER A SCREEN HAVING A MESH SIZE SUCH THAT ONLY SAID SOLID OXIDE PARTICLES PASS DOWNWARDLY THROUGH THE SCREEN.
