Combustion and carbonization of olive-pomaces dried using solar process

Abstract : In the last decades, many efforts were focused on the thermochemical transformation of agricultural and industrial residues to generate energy, chemicals or activated carbons. The present study concerns olive pomaces (O.P) materials coming from the Region of Meknès – Tafilalet. These residues result from the olive oil extraction process (pulp and stones).The studied samples are raw and pressed O-P, dried at various temperatures (40°C-60°C-80°C) in using thermal solar energy.The physico-chemical characteristics of these samples and of hemicellulose (H.), cellulose (C.) and lignin (L.) compounds are compared, before and after their carbonization. The thermal treatments of such materials lead to chars which can be used as precursors for the synthesis of activated carbons.
