is working on fixed-bed two-stage biomass gasification. He began his work doing experimental research on an experimental gasification plant named Test Gasification Plant (T.G.P.) installed at UCL. The investigations focused on parameters specific to multi stage gasification like the air ratio (distribution of air between reaction zones). The investigations included research on the use of wasted biomass as fuel for the gasification process. The main challenges of gasification stand in the destruction of impurities found in the producer gas at the outlet of the gasifier. The major part of these impurities, tars, is a residue from pyrolysis. He is thus now developing a simple numerical model to improve the prediction of the pyrolysis process taking place in the two-stage gasifier.
