Abstract:
Agroindustrial biomass residues are a potential renewable energy source for developing countries. Gasification of coffee shells, oil palm shells and wood is performed in an electrical indirectly heated cocurrent fixed bed gasifier. The process was carried out at 850 and 900 °C with steam as reaction agent. Biomass inputs were varied from 0,20 to 0,35 kg/h. The characterization of the raw materials includes the proximate analysis (water, ash and volatile matter contents) and the ultimate analysis. The facility is equipped with an evolved gas analysis system and gas chromatography. The detected gas compositions contain CO (40 – 50 %), CO2 (2 – 7 %), CH4 (1 – 2 %) and H2 (50 – 52 %); gas densities vary from 0,66 to 0,88 kg/m3 and the higher heating values from 12 to 14 MJ/kg.
