DESIGN AND MANUFACTURE A SMALL UNIT FOR ACTIVATED CARBON PRODUCTION FROM SOME AGRICULTURAL RESIDUES

Abstract

Agricultural residues are considered as a national wealth untapped.Itcan be caused pollution of all environmental elements, because of burning and disposing in different ways. These residues can be used in many products such as organic fertilizer, animal feed, bricks, bioenergy, coal organic, and many of innovative products such as bio-char, activated carbon, polymers, furfural and etc.... Activated carbon is materials frequently used in many fields. It is a form of carbon that has been processed to make it extremely pores and thus to have a very large surface area available for adsorption. Adsorption capacity of activated carbons depends essentially on its initial structural properties, pre-preparation and preparation methods. Therefore, activated carbon is widely used in gas purification, gold purification, metal extraction, medicine, sewage treatment, air filters in gas masks and filter masks, along with water and wastewater treatment also as catalyst support and many other applications. Activated carbon is almost non-existent in Egypt. Although normally used, the activated carbon is imported from abroad (Ministry of Industry and Trade, 2016) and a few quantities that are produced locally does not exceed production laboratory, which is used in the experiments and researches.
