A process development for gasification of rice husk

Abstract

Rice husk has been recognized as a potential source of energy. Thus, the main objective of this work was to develop a rice husk gasification process. Diffuse reflectance infrared spectra reveal that partial oxidation of rice husk at reaction temperatures below 1000 K would also allow recover valuable of amorphous silica materials. In the laboratory-scale fixed-bed and bench-scale downdraft experimental approaches, gasification of rice husk was accompanied by a substantial production of syngas at 760–900 K. It appears that in order to generate 10 kW electric power, approximately 28 kg/h of rice husk must be gasified. The rice husk gasification process, in terms of heat requirements, can be self-sustaining.
