The present invention generally relates to a system for producing activated carbon from cow dung. The process begins with a drying and washing unit to pre-treat the raw material. Dried cow dung is then milled and sieved to a specific particle size. A second drying step prepares the sieved material for carbonization in a nitrogen atmosphere. The resulting carbonized material undergoes chemical activation using a sodium hydroxide solution. Subsequent pyrolysis in a nitrogen environment further develops the pore structure of the activated carbon. The pyrolyzed material is then washed with hydrochloric acid to remove impurities. A final drying step yields the desired activated carbon product, which is then crushed. This system provides a controlled and efficient method for converting cow dung into valuable activated carbon, offering a sustainable waste management solution and a source of high-quality material for various applications.
