O-05 食品廃棄物の超臨界水ガス化による再生可能熱の創生(糖化・エネルギー,口頭セッション)

The supercritical water gasification (SCWG) of wet-biomass holds promise as a technology to convert biological waste wet biomass into valuable, environmentally, and friendly energy. The 24 h continuous operation with the pilot plant (1 t-wet/d) has been conducted and it was successful achieved by appropriate content suspended activated carbon (a. c.) as gasification catalyst. The a. c. content increase makes the decrease of TOC in gasification effluent. The adsorbed TOC quantity onto a. c. from gasification effluent was determined by the adsorption test with SCWG effluent by a. c.. and the constants of Freundlich equation at 25 ℃ was determined as K=2.09, 1/N=0.7588, respectively. The estimated TOC value by this equation suggests the catalytic decomposition ability of a. c. in SCW.
