<p><P>PROBLEM TO BE SOLVED: To provide a digestion gas purification apparatus which can approximately perfectly remove organic silicon compound components in a digestion gas, even when the organic silicon compound components are contained in large amounts in the digestion gas, and can hold high efficiency over a long period. <P>SOLUTION: This digestion gas purification apparatus having at least an activated carbon adsorption tower 4 having an introduction portion 40 for introducing the digestion gas containing siloxanes, filled layers 41, 42 filled with activated carbon adsorbent for adsorbing off the siloxanes in the digestion gas, and a discharging portion 43 for discharging the treated gas is characterized in that the activated carbon adsorbent is a combination of at least two adsorbents including an activated carbon adsorbent I having a specific surface area of≥800 m<SP>2</SP>/g, fine pore distribution peaks of 15 to 30Å, pore volumes of≥0.25 mL/mL at peaks, and pH≥9.0 with activated carbon adsorbent II having a specific surface area of≥800 m<SP>2</SP>/g, fine pore distribution peaks of 5 to 15Å, pore volumes of≥0.20 mL/mL at peaks, and pH≥9.0. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
