Abstract:
In this work, a novel approach to the treatment of biomass gasification wastewater, i.e. liquids deriving from wet gas cleaning operations, is explored. The proposed technology is based on adsorption on biomass gasification char, which is continuously produced by the plant itself. Samples of char were taken and characterized and then their adsorption isotherms were experimentally determined. Batch tests were conducted in a solid¬liquid contactor and a deterministic dynamic mathematical model was used for data interpretation. Results showed that the proposed process is able to achieve an extremely high reduction in the pollutants content, by using an adsorbent material which is practically costless.
