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 improvement of the equipment utilization efficiency of the SCWG facility on-site is important. The 24 h continuous operation with the pilot plant (the treatment capacity is 1 t-wet/d) was successful with stable pressure loss of heat exchanger. However, SCWG plant might be operated by daily start and stop on weekday, because Shochu brewers work on weekday daytime. Therefore, the bad influence to tar characteristic by the rise drop of the temperature and the pressure of daily start and stop was concerned about. Therefore, the daily start and stop gasification tests were conducted during 4 days included 3 days holiday. The heat exchanger tar plugging was concerned, however the result of test indicated no tar plugging sign. The product gas elemental analysis results and the carbon gasification efficiency rates indicated no influence sing of Daily start and stop operation.
