The Palm oil industry produces large amounts of biomass as fuel and burns up much of it as fuel for power and strange generation. How can one simultaneously produce activated carbon?
Palm oil biomass residue were well known for making the activated carbon. Its difficult to make activated carbon in palm oil industrial furnace, because there you need to maintain the oxygen deficient condition in the furnace. If make furnace, oxygen deficient then you unable to meet you energy demand that's you need during industrial operation.
On other hand you may use the residue obtained after oil extraction directly for activated carbon production in another optimized furnace. A number of articles present on sciencedirect, ACS etc., you may opt them for methodology and optimizing the preparation condition.
