Abstract
The biomass waste (Bw) are abundant and high potential as an activated carbon (AC) precursors. In this study, Bw has been converted to biomass waste AC (BwAC) via chemical-physical activation from ketapang, coconut, candlenut shell, and pepper husk carbon precursors immersed in chemical activator with H3PO4 then pyrolysis at 650°C. The influence of Bw sources on the pore structure development was investigated and discussed. Coconut shell carbon precursors successfully convert to activated carbon with the highest surface area and pore volume relative to the others. Lignocellulosic content plays an important role. The high lignocellulosic content has the most appropriate structure for porosity development, especially microporosity.
