The supercritical water gasification (SCWG) of wet-biomass holds promise as a technology to convert biological effluent into fuel gas, environmentally and friendly energy. Shochu is Japanese popular distilled liquor and Shochu residue is waste, as organic effluent by-produced at distillation process in Shochu distillers. Shochu residue is problem for Shochu distiller because of high treatment cost. SCWG is expected for solution for this problem; however one of major obstacles was tar plugging in heat exchanger tube of SCWG facility. 24 h continuous test and 60 h DSS test of SCWG for Shochu residue with pilot plant (1 t-wet/d) has been conducted and achieved by adding radical scavenger and using rapid heating rate. The difference of radical scavenger concentration was considered by some verification test and we report the results.
