CHLORINE CAPTURING DURING PYROLYSIS OF REFUSE-DERIVED FUEL

THE CHLORINE CONTENT OF CARBONACEOUS CHAR DERIVED FROM THE PYROLYTIC CONVERSION OF REFUSE-DERIVED FUEL (RDF) IS HIGHER THAN THAT OF CONVENTIONAL COAL. THE PROPOSED RESEARCH WILL DETERMINE IF THIS CHLORINE CAN BE "CAPTURE" DURING THE PYROLYTIC CONVERSION BY THE ADDITION OFCA(OH)2 OR NAOH, AND THE EXTENT TO WHICH IT CAN BE "CAPTUREDTHE RESEARCH WILL IDENTIFY THE RELATIONSHIP BETWEEN THE AMOUNT OF CHLORINE REMOVAL AND: 1) THE ALKALI/RDF RATIO 2) QUANTITY ADDED AND METHOD OF DISTRIBUTING THE ALKALI, AND3) THE COMPOSITION OF THE RDF. THE RESULT OF PHASE I WILL DEMONSTRATE THE FEASIBILITY OF REMOVING CHLORINE DURING PYROLYSIS OF RDF IN THE LABORATORY.THE RESULTS OF PHASE II WILL DEMONSTRATE THE FEASIBILITY OF CHLORINE REMOVAL USING A TWINSCREW PROTOTYPE EXTRUDER OF THETYPE PROPOSED FOR COMMERCIAL APPLICATION. FROM THIS WILL COME SUFFICIENT DATA TO ENGINEER THE REMOVAL OF CHLORINE IN THE COMMERCIAL SCALE PYROLYSIS UNIT. THE SUCCESSFUL COMPLE-TION OF THIS RESEARCH WILL FACILITATE THE DEPLOYMENT OF AN ENVIRONMENTALLY SUPERIOR WASTE DISPOSAL SYSTEM COSTING LESS THAN HALF AS MUCH AS MASS INCINERATION ALTERNATIVES.
