PROJECT DESCRIPTION
Biomass gasification in supercritical water is a rather new and challenging process. The reactions take place at high temperatures, high pressures in a water environment. The design of the reactor is important with respect to complete conversion of the reactants and avoiding the production of by-products that can plug or damage the reactor. Because of the use of wet biomass (sewage sludge) heat exchange between products and reactant is required for a high process efficiency. Heat transfer, hydrodynamics and phase changes are important aspects for an optimum design of such a heat exchanger. For both the reactor and heat exchanger mathematical models will be developed and validated against experimental data of the pilot-plant. The models will be used for further optimization of the reactor and heat exchanger.
