Abstract: Experimental gasification studies are reported for highly reactive peanuts, palm and cashew nut shells chars from Ziguinchor area in order to aliment a local clay brick baking unit. The gasification tests were operated in a fixed bed reactor under steam and/or carbon dioxide at three different temperatures (950 °C, 1000 °C and 1050 °C), in order to investigate the experimental conditions of three samples at different particle size. The gasification of char conversion at different temperatures is found to be dependent on gasifying agent, nature of the sample, and can be explained by the Arrhenius equation, thus suggesting the use of three different models: Volume Reaction Model (VRM), Random Pore Model (RPM), and Shrinking Core Model (SCM) in order to interpret the carbon conversion data and to determine the kinetics parameters.
