This experiment manufactured charcoal material with agro-forestry wastes such as coconut shell fiber and oil palm fiber by treating these fibers with NaOH and different temperatures. Properties obtained are as follows: 1. Holocellulose content of oil palm was higher than that of coconut fiber. Hence, oil palm got more charcoalization than coconut fiber. 2. The ash content of charcoal material from non-wood fiber was pretty rich with inorganic materials. 3. Methylene blue adsorption capacity of low temperature charcoal (400℃) was lower than that of high temperature (800℃) ones. Results also indicated that liquid phase adsorption of high temperature charcoal was higher than that of low temperature charcoal in supersonic.
