Abstract

The vapogasification of biomass in a Circulating Fluidized Bed has been studied in order to enable the design and the erection of an industrial process. Theoretical and experimental tools have been designed to allow an engineering approach. In order to understand the hydrodynamic behaviour of the reactor, a pilot plant has been designed and erected to feed 20 kg/h of biomass. An exhaustive study of process parameters has been carried out, to determine predominant parameters for the process global control. Operating the built system has also permit to understand attrition phenomenon of polydisperse particles (olivine and char) in the Circulating Fluidized Bed. In order to complete those results, a study of mixing and segregation of those polydisperse particles has been carried out in fluidized bed with both experimental and numerical (CFD-3D MFIX) approaches. A significant contribution has also been done to numerical models assisting biomass vapogasification in Circulating Fluidized Beds design: 0D, 1D, bubble-emulsion, population balance).
