Usually air/oxygen gasification is used in industrial application due to its self sustained characteristic. This process, operated close to 600qC requires no external energy consumption due to partial oxidation sequence within. When applied to high humidity products a previous drying stage is required. In this case the energy consumption increases and the overall energy balance shifts to steam gasification one. It is well-known that steam gasification provides a superior syngas in terms of low heating value and hydrogen content. A solution could be the injection of water from the drying stage into the gasification one. Therefore we chose the pyro-steam-gasification as analyzed process.
