Conversion of biomass to energy using solar energy
Actions
PhD work of V. Pozzobon
The efficiency of classical biomasss gasification processes is lowered due to the fact that the involved chemical reactions are endothermic, and that part of the biomass has to be oxidized to supply the required enegy.
The project is to supply this energy as concentrated solar energy in new types of reactors, in which solar radiation will enter into direct contact with ground biomass solid particles. The PhD work focusses on understanding and modelling the thermochemical conversion of a single particle submitted to high density solar fluxes, such as several thousands or tens of thousands kW/m2.
New laboratory experimental devices are under development. A numerical model including drying, pyrolysis, char gasification and gas phase reactions is being developed.
This project is carried on in the frame of the SOLSTICE Labex, in collaboration with PROMES laboratory.
