Gasification tests were carried out in an internal circulating bubbling fluidized bed reactor injected by water steam and oxygen, working at thermal input of about 4 kW. The input streams to the gasifier (biomass, water steam and oxygen) and output ones (char, water and syngas) were quantified to characterize the chemical efficiency of the process. The produced syngas having a GC­MS tar content of 10.1 g/Nm3dry, which molecular composition was carefully ascertained, was cleaned in...
