O-201 Ni触媒の下水汚泥を用いた低温接触ガス化による軽質ガス製造および窒素化合物の乾式ガス処理法(セッション3:技術・導入-ガス化等-,口頭発表)

抄録

The production of light fuel gases by catalytic gasification of sewage sludge at low temperatures was investigated. Gasification of sludge was carried out at the temperature range of 773-973K with two stage fixed-bed reactor in argon atmosphere. Ni/Al_2O_3 and LY-Ni were used in this work. When the nickel catalyst was used, tarry materials and NH_3,HCN were remarkably decomposed, and the yield of the gas increased. The main component of product gas was hydrogen. The reforming of tarry materials and nitrogen compound progressed at temperature as low as 973K using Ni-catalyst.
