چکیده:

Determination of pore size distribution of the porous materials is used for design and improvement of several systems including heterogeneous catalysts, mass transfer in porous materials, separation processes, removal of various pollutants, gas storage and physical adsorption. Three activated carbons are synthesized in a rotary reactor at different activation times. The adsorption isotherms of the samples are measured .The pore size distribution of the samples is determined using combined Saito and Foley method. An average potential function has been determined inside the cylindrical pores. The effect of activation time on the pore size distribution samples was investigated
