Reacting solids

Waste and energy recovery and valuable materials production

Solids incurring reactions where they consume, in partial and total oxidation, or produce (i.e. soot formation, materials synthesis) are quite common in industrial applications.


We developed customized set-ups to measure the loss/gain of weight in controlled atmosphere, with on-line monitoring of the gas products and possibly video recording of the shape evolution.


That allows to characterize biomass, waste, carbon oxidation or partial oxidation, in view of the energy exploitation, the reduction of the environmental impact, the prevention of spontaneous exothermic reactions.


Other applications involve the flame-assisted synthesis of catalytically active complex oxides or production of soot nanoparticle and carbon nanotubes.
