Abstract
<p>Large amounts of rice husk char (RHC) and rice husk ash (RHA) are generated in rice husk-based power plants, and development of an effective recycling method for the RHC and the RHA wastes would be desirable. The main components of RHC were carbon (37.2 mass%) and silica (47.72 mass%), while that of RHA was silica (88.59 mass%). Both RHC and RHA had a reticulate porous structure with specifi c surface areas of 207.0 and 7.9 m2/g, respectively. Their ammonia recovery capacities were evaluated by adsorption capacities of ammonia in gas phase (50 ppm) and its desorption capacities in water at 25°C and ambient pressure. The adsorption capacity of ammonia in gas phase was higher for the RHC than for the RHA.</p>
