| Tiivistelmä (eng): | Supercritical water gasification has great potential to address important problems associated with wet biomass handling and provides a mean for high conversion of biomass to fuel gases such as hydrogen and methane. However, the process is limited to lab scale due to the challenges related to demand for heat and power at high process conditions, complicated process kinetics, salt corrosion and plugging, and wet biomass feed handling. In order to address these issues, better understanding of the continuous process dynamics is required within the supercritical water medium. This research focuses on understanding and modelling a pure water based supercritical water gasification system available at Åbo Akademi University in Turku, Finland. This research studies a system response in semi-batch configuration with water as the only process medium. The results from the process model have shown to fit well with the experimental results and the model findings and conclusions will be used in the design of a continuous feed system. The study has also identified several potential areas of improvement in the current system. The process model developed will form the basis to understand the process kinetics at the given equipment for a real biomass feed. |
