This project is for the production and marketing of activated carbon from rice husks. The activated carbons are widely used for the absorption of toxic gasses. Therefore, this product has a good marketability with proper linkages of the manufacturers, especially in the sugar industry and in the sewerage industry. The revenue potential for this idea is estimated at US$202,800 per annum, with a net profit of 50%and a payback period of 1 year and 2 months.
The process of making activated carbon from rice husks consists of crushing the rice husks in a hammer mill to required size and then pulverizing them in a ball mill. The husk powder is digested with zinc chloride. The mass is then activated at elevated temperature. The activated pellets are quenched and leached counter-currently by diluted hydrochloric acid and dried in a tray drier.
