| Title | Fluidized bed gasification of biomass from plant-assisted bioremediation: characterization of products |
| Abstract | In this work, the analysis of the potential and the issues of gasification of biomass produced from pruning from plant-assisted bioremediation (PABR) is presented. Such biomass contains a small but not negligible content in metals (mainly Cu and Zn) extracted from a contaminated soil. Even if most of the metals analysed are confined in the roots and then the risks of release of hazardous materials in the atmosphere is really very limited, we analyzed all the steps of the gasification process aiming at tracking the heavy metals, tars and other hazardous compounds to assess a safe procedure for trapping them. The biomass pruning, after preliminary TGA-DTA analysis, are used to produce syngas in the fluidized bed gasification plant located at Sapienza. The paper analyses the distribution and the composition of the solid particles and the volatile compounds released from the gasification process, allowing to determine that most of the metals are concentrated in the ashes while their content in the syngas is negligible. |
