ABSTRACT. Activated carbon is an effective fettering material, highly porous with immense surface area. Activated carbon removes many organic and some specific inorganic substances such as chlorine, cadmium, nickel, lead, and chromium from common industrial pollutants. Activated carbon was produced form walnut shell and groundnut shell by two ...

Walnut shell, a good precursor for activated carbon production, is a major agricultural waste in China. According to statistics, there is more than 100,000 tonnes of walnut shells are produced in China annually. To make better use of the cheap and abundant agricultural waste, it is proposed to use it for activated carbon production.

For peanut shell-based activated carbon production, some studies have been carried out to prepare activated carbon using only variety of chemical activators, such as KOH and H 3 PO 4. This method involves a complex recycling of the activating agent and generates experimental wastewater discharge that requires effluent treatment.

The economic potential of activated carbon (AC) synthesis from walnut shell biomass for CO 2 capture was evaluated in the present study. For this purpose, the chemical activation was employed to manufacture ACs and the effect of different impregnation ratios of activation agents, comprising KOH (KH) and H 3 PO 4 (HP), onto the properties of fabricated ACs was examined.

tion process to produce activated carbon (Pollard et al., 1992). Coconut shell could be a good potential biomass material for acti-vated carbon production due to its hardness, consisting mainly of lignin and cellulose, and higher density compared to other biomass, hence making it much easier to process (Gratuito et al., 2008).
