Syntheses and Modelling of the Activated Carbon Made by Olive Cake Residues by Pyrolysis and Actived by a Water Vapour Current at One Process

Fethi Nebili and Faouzi Bouachir    

Abstract: Now-a-days, it is indispensable to contribute to the durable development by using a local biomass and more particularly to the valorisation of the olive cake residue to carry out a raw local autonomy material, a clean process, saving in atoms and energy autonomy. Within this framework and considering the availability of the olive cake residue in Tunisia and the absence of its thermochemical valorisation (pyrolysis, gasification and combustion), researchers were interested in this research in the study of slow pyrolysis between 500 and 800°C of this biomass and its activation in only one stage in automatic and programmable oval furnace. The furnace is equipped with a sample door out of stainless of cylindrical form tight in a water vapour current. The choice of the activation method is guided by the preoccupation with a simple process development of application. The study of the productivity of the method indicated reveals a significant output. The products obtained are characterized by specific microspores surfaces Smi between 400 and 800 m2 g-1. The technique of the experimental design helps us to optimize the process and to minimize the numbers of the tests. The increasing request of the activated carbons, however relates to the field of water and the environment.
