碩士 === 東海大學 === 化學工程學系 === 87 === Abstract The purpose of this thesis is to develop an active and selective catalyst for the hydrogenation of SO2. Iron compounds supported on r-Al2O3 and SiO2 were studied. The catalysts used including: (1) Fe/ r-Al2O3 prepared from FeSO4·7H20, (2) Fe/ r-Al2O3 made from Fe(NO3)3·9H2O, (3)Fe-Cr-Si. The reaction tests were performed at several reaction temperatures by using catalysts with various atom ratios. For the 1st type catalysts, we found that 200% Fe/ r-Al2O3 had the best catalytic performance (conversion of SO2 and selectivity of H2S). For the 2nd type catalysts, 300% Fe/ r-Al2O3 had the highest catalytic activity. For the 3rd type catalysts, experimental results indicate that Fe-Cr-10Si has the best performances among the catalysts we have studied. The characterization of all the catalysts were performed by SEM、XRD、ESCA and BET.
