Preparation of activated carbon from lignocellulosic biomass
Generally, two main steps are involved in preparation of
activated carbon from lignocellulosic biomass. The method is
started with carbonization of lignocellulosic biomass at temperature
lower than 800 8C in the absence of oxygen [1,12,18,21,39].
The process is then followed by activation process for the
development of surface area and pore volume of activated carbon.
Activation process can be divided into two different methods,
which are physical activation and chemical activation.
