The installation is a cylinder fixed bed reactor. An electric resistance externally heats the tube reactor made of refractory steel. The electric heating system offers the advantage of precise heating rate and constant temperature period control. The treated sample is introduced within a refractory longitudinal steel crucible in the active zone.The reactor tube has two gas inlets for different experimental conditions: air, inert gas (nitrogen) or steam. These two inlets have flow regulators that give the possibility to modify the treatment process configuration.
