The use of walnut shell-manufacturing activated carbon
   Because the chemical composition of walnut for more carbon, and activated carbon is one kind has developed the pore structure, large specific surface area and excellent adsorption performance carbon. Tap water factory, sewage treatment plant, pure water, pharmaceutical factory, chemical and food factory, citric acid factory, solvent factory, fuel plant, the hotel, the family all need to use the quality of their products to complete the activated carbon filter, adsorption, separation or decoloring and process technology. With the rapid economic development, China needs more and more of activated carbon, and the market prospect of the development of activated carbon is very wide.
   With mountain walnut as raw material, using legal system not to finalize the design water vapor activation for granular activated carbon. The test results show that the effect of the comprehensive were 12% ~ 16%. By the system activated carbon such as the methylene blue decoloring force as the main target, best activation temperature of 850 ¡æ ~ 950 ¡æ, the best activation time for 3 h ~ 4 h; Such as the iodine value as the main target adsorption, best activation temperature of 950 ¡æ, the best activation time for 3 h.
