Abstract

Abstract: By single step pyrolysis and different chemical activation (KOH and ZnCl2 ) with different concentrations of 0.3 M, 0.5 M, 0.7 M, and 0.9 M, activated carbon monolith based on jengkol Pithecellobium jiringa shell wastes is obtained. The Samples are prepared in monolith form. The pyrolysis process begins with carbonization from room temperature to 600ºC in the N2 gas environment and followed by physical activation in the CO2 gas environment at a high temperature of 850 ºC for 2.5 hours. Monolith carbon is observed in the change of dimensions, mass, thickness, volume, and density. That it was observed that the pyrolysis process which includes carbonization and activation effectively reduces all the dimensions, mass and density parameters of carbon monoliths. Furthermore, the concentration of chemical activators dramatically exhibits excellent effects with increasing concentrations of activator agents, indicating that the porosity and highly micro-, and mesopores structure of activated carbon monoliths. This study is a model and reference for producing high-porous activated carbon from biomass waste for different practical applications.
