<P>PROBLEM TO BE SOLVED: To obtain a system for decomposing and removing tar in a gasified gas, which is obtained by gasifying a biomass gas containing a sulfur component, that is, a sulfur content by utilizing a catalyst having a hybrid function. <P>SOLUTION: In the system utilizing the catalyst having the hybrid function for decomposing a tar content in the gasified gas generated by the thermal decomposition of the biomass gas, (a) the catalyst having the hybrid function is BaTiO<SB POS="POST">3</SB>, (b) the BaTiO<SB POS="POST">3</SB>containing BaCO<SB POS="POST">3</SB>is generated by using Ba<SB POS="POST">2</SB>TiO<SB POS="POST">4</SB>as a CO<SB POS="POST">2</SB>-absorbent, (c) after that, the BaTiO<SB POS="POST">3</SB>containing the BaCO<SB POS="POST">3</SB>being a product at the (b) is used as a tar decomposition catalyst, (d) CO<SB POS="POST">2</SB>is separated and the Ba<SB POS="POST">2</SB>TiO<SB POS="POST">4</SB>is generated by regenerating the BaTiO<SB POS="POST">3</SB>containing the BaCO<SB POS="POST">3</SB>which is used as the tar decomposition catalyst, and (e) the Ba<SB POS="POST">2</SB>TiO<SB POS="POST">4</SB>being a product at the (d) is recycled and utilized. <P>COPYRIGHT: (C)2012,JPO&INPIT |
