PROCESS FOR MAKING CHEMICALLY ACTIVATED CARBON

摘要

A method for making activated carbon includes heating a mixture of a carbon precursor or a carbonized precursor and a chemical activating agent in a furnace. The furnace includes an internal surface either formed from or lined with a corrosion resistant material such as high purity silicon carbide or silicon nitride.
