Abstract

CHEMICAL UTILIZATION OF CARBON DIOXIDE OBTAINED FROM LARGE SCALE STATIONARY SOURCES SUCH AS COAL, OIL AND NATURAL GAS INDUSTRIES IS ONE POSSIBLE PATHWAY TO DECREASE THE RATE OF CARBON EMISSIONS. CATALYSIS PLAYS A CRUCIAL ROLE IN THESE CARBON DIOXIDE UTILIZATION REACTIONS.IN THIS RESEARCH, THE SYNTHESIS OF A CLEAN FUEL SUCH AS, DIMETHYL ETHER (DME) VIA CO2 HYDROGENATION HAS BEEN INVESTIGATED ON BIFUNCTIONAL CATALYSTS COMPOSED OF CU-ZNO-AL2O3-ZRO2 AS HYDROGENATION COMPONENT AND NA-MORDENITE AS DEHYDRATION COMPONENT WITH DIFFERENT ZRO2 AND AL2O3 CONTENTS. THE SAMPLES WERE SYNTHESIZED BY CO-PRECIPITATING SEDIMENTATION AND CHARACTERIZED BY BET SURFACE AREA MEASUREMENTS AND X-RAY DIFFRACTION. RESULTS SHOW THAT BOTH ZRO2 AND AL2O3 HAVE SIMILAR EFFECT ON CONVERSION FOR ALL CATALYSTS, BUT AL2O3 PROFOUNDLY INCREASED SELECTIVITY OF THE DME. BESIDES, WHEN THE TOTAL CONTENTS OF AL2O3 AND ZRO2 WAS INCREASED ABOVE 16 WT%, THE CONVERSION AND SELECTIVITY TOWARD DME FORMATION WERE REMARKABLY DECREASED WHICH MAY BE RELATED TO LOWERING OF THE AMOUNT OF ACTIVE SITES OF COPPER ON HYBRID CATALYSTS.
