Summary

THE EFFICIENCY OF A COMMERCIAL CATALYTIC REACTOR TO REMOVE ETHYLENE FROM COLD ROOM ATMOSPHERES WAS TESTED. THE WORKING CONDITIONS (QUANTITY OF ETHYLENE, AIR FLOW, TIME OF PERIODICAL REVERSION OF GAS DIRECTION, TEMPERATURE AND ACTIVITY OFTHE CATALYTIC BED) WERE TESTED. A COMPARISON WAS ALSO MADE BETWEEN THE CATALYTIC SYSTEM AND CHEMICAL ABSORPTION (POTASSIUM MANGANATE IN A SOLID BED). THE CATALYTIC SYSTEM GAVE GOOD RESULTS, BOTH WITH REGARD TO THE HIGH CONVERSION RATE OF ETHYLENE AND THE POSSIBILITY OF REGENERATING THE CATALYTIC BED WHICH ENABLES AN EXTENDED WORKING TIME. WITH REGARD TO THE POTASSIUM MANGANATE ABSORPTION TECHNIQUE, THE HIGH YIELD OF THE CHEMICAL ABSORPTION SYSTEM WITH THE RAW ADSORBENT WAS CONFIRMED, BUT ITS RAPID DECAY WAS ASCERTAINED WHEN LARGE AMOUNTS OF ETHYLENE HAVE TO BE REMOVED FROM COLD ROOM ATMOSPHERES.
