Abstract:

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 a scrubber. Two different scrubbing liquids were tested: environmentally friendly bio­diesel and water. Their tar removal efficiency was determined measuring the tar content of the syngas downstream of the scrubber. It was ascertained that the bio­diesel scrubbing removes 99% of the tar in syngas, while the water scrubbing removes 89 %.
