At present, China consumes 250 million MR of wood annually, and imports 3 billion US dollars of wood

The preparation methods of activated carbon include physical method, chemical method, microwave radiation method, etc.(1) Physical method.china active carbon/

Physical method is to use carbon dioxide, water vapor or the mixture of both as activator, the carbonized carbon material and gas in the activation furnace at 500~1200℃ for carbon activation reaction, so that the pore size of the carbonized material to expand, the formation of activated carbon with porous microcrystalline structure.Gas activation method mainly includes carbonization and activation engineering.The so-called carbonization, refers to the low temperature (about 500℃) is small, the volatile coal tar molecules in the material and the thermal decomposition and curing process of asphalt, that is, to remactivated carbon pellets wholesale
