Abstract:
The supercritical water gasification (SCWG) of wet-biomass holds promise as a technology to convert biological waste (wet biomass) into valuable energy. The improvement of the equipment utilization efficiency of the SCWG facility on-site is important. Therefore, the 24 h continuous operation with the pilot plant (the treatment capacity is 1 t-wet/d) was conducted and it was successful with stable pressure loss of heat exchanger. However, SCWG plant might be operated by daily start and stop (DSS) on weekday daytime when shochu makers work on. The bad influence to tar characteristic was concerned about by the rise and drop of the temperature and the pressure with DSS. Therefore, the DSS gasification tests included 3 days holidays were conducted during one week. The heat exchanger tar plugging was concerned about; however the test results of the heat exchanger pressure loss indicated no tar plugging sign. The product gas elemental analysis results suggested the increase of gasification catalyst effects by gasification tests. The carbon gasification efficiency rates indicated no influence sing of DSS operation.
