Recovery of energy and nutrients from urban and industrial residues
Catalytic Supercritical Water Gasification Of Wastes: Comparison Between Sewage Sludge And Sugar Beet Vinasse
Short Introductive summary
The existence of residues that are difficult to treat has encouraged the development of new technologies aimed at converting them into value-added products. In this internship, the supercritical water gasification process was adopted for sewage sludge and vinasse, in order to maximize the gas production such as hydrogen and methane. The products of the process (gases, liquids and solids) were characterized, and the temperature and catalysts influence, analyzed and compared between the both wastes. The presence of catalysts provided an effective increase in gas production, even at low temperatures (450 °C), generating gases with a calorific power of 14.05 MJ/Kg for sludge and 12.78 MJ/Kg for vinasse. This indicates a viable way of treating these residues and gases/energy production from sustainable sources.
