Papa A.A., Di Carlo A., Rapagnà S., 2022, Biomass as a Renewable Source to Produce Synthesis Gas by Catalytic Gasification Process, Chemical Engineering Transactions, 92, 295-300.
Technical feasibility to reduce tar concentration in the gas obtained by steam gasification of biomass by using a continuous biomass gasification plant, mainly composed of a fluidized bed gasifier with an internal diameter of 0.1 m containing in its freeboard a ceramic candles filled with commercial catalyst pellets used for the steam reforming of naphtha was verified. The tests have shown that it is possible to obtain a tar reduction in the producer gas comparable to that obtained by using a vegetable oil absorption plant. This process configuration allows you to reach greater energy efficiency of the entire gasification process as the transformation of tar compounds into light gases such as H2 and CO. The catalyst strongly reduces the concentration of NH3 to levels of about 30 ppm and methane to concentrations below 1% by volume.
