The resulting moist paste upon mixing the char with ZnCl2 was charged into the furnace and heated in inert atmosphere for 60 minutes to a final temperature of 600, 800 and 1000oC. Cold water was used to quench the activated carbon produced, and this further dried for 60 minutes at 110oC, till a constant weight of activated carbon was obtained. After the chemical activation, the activated carbon was rinsed thoroughly. Washing was used to remove the remaining zinc chloride and ash in the carbon. This was accomplished by washing with distilled water. The activated carbon was then drained and spread on a tray at room temperature. The activated carbon was dried in an oven at a temperature of 110oC for 3 h. Weight of activated carbon produced was taken and yield calculated.
