ENERGY; How to make Activated Carbon

Activated carbon (AC) is highly porous material consisting millions of small pours that gives the material a wide surface area. The structure of the pores and its wide surface area gives the AC an astonishing adsorbing ability. It’s used in a variety of industrial application for its ability to clean contaminations in gas and liquid flows. Practically any raw material containing carbon can be used to produce AC, although the most used raw materials for producing is nutshells and wood.


Sawdust from pine, which is a common tree over the World, can be used as the raw material for producing AC. Different parameters; the temperature in the oven, the choice of base and the impregnation ratio of the base compared to the biomass give different variants of AC. Each parameter was set to have three different levels except for the usage of only two bases.


The different levels of the parameters are; temperature 400 C, 450 C and 500 C, bases can be potassium hydroxide (KOH) and sodium carbonate (Na2CO3) and the relative impregnation 1-, 1,5- and 2* mbio where mbio is the weight of the biomass and gives the relative impregnation 1:1-, 1.5:1-, 2:1 (msolution* mbio).  Also which setup that would give the best yield should be investigated.
