Massimiliano Materazzi (Chemical Engineering Department): Clean energy from waste: fundamental investigations on high temperature bubbling fluid bed gasifiers

Biomass is the third largest primary energy resource in the world, after coal and oil. Wide scale use of biomass could help postpone fossil fuel depletion and reduce global warming. Gasification of biomass is an attractive technology which utilizes municipal solid waste-based fuels to produce syngas (CO2 and H2) suitable for power production using energy gas engines or turbines. Fluidized bed gasification, because of its fuel flexibility, high efficiency and low environmental impact, is one of the most promising means for biomass energy conversion.
This work is centered on gaining a more fundamental understanding of particulate behaviour in the fluid bed and how this may impact operational issues including the fate of the ash forming components (ie agglomeration and defluidization) and the behaviour of the volatile matter. This will provide improvements and enhancements to be made to the design of gasification plants, hence enabling their successful development and take up.
