Nano Pores Surface Area Evaluation In Palm Kernel Shells And Masonia Wood Derived Activated Carbons.

Abstract

Biomass charcoal was obtained by pyrolysis from Palm kernel shells, Coconut shells and Masonia wood precursors as 33.2%, 30.6% and 24.7% respectively. The conversion of the charcoal to activated carbon was implemented with KOH activation. The active surface area measurement carried out with methylene blue adsorption and Brauner, Emmet and Teller (BET) surface adsorption theory gave values of 80.3m²g^-1, 172.14m²g^-1 and  140.08m²g^-1 respectively. The developed pores were in the mesopores category of pores.
