Self-sustained single-step activation in situ process for activated carbon synthesis from agro residues

Activated Carbon which is used in purification applications is produced from biomass (mainly coconut shells). Currently, it is produced using a two-stage physical activation method. That is in stage one raw material biomass is converted into intermediate product charcoal and then in stage two, the produced charcoal is converted into activated carbon. Also, the heat required for the process is mainly supplied using non-renewable means. In this innovation, Activated carbon is produced in a single step directly from biomass by an in-situ process. The system does not use any external heat source. Rather, the heat required for activation is taken from the energy of volatiles which is generated within the system
