PREPARATION OF ACTIVATED CARBON FROM PETROL COKE IN REFINING FACTORY

Activated carbon was prepared from petrol coke with addition of activating agent at higher temperature. Effects of activating agents, activating agent/coke ratio and activated temperature on methylene blue decolorizing capacity and BET specific surface area were studied. The optimal experimental condition was also obtained.Adsorption isotherms of CH 4 on two kinds of activated carbon (one prepared in our lab and the another prepared in Ningxia activated carbon factory) have been measured by two vessel volumetric method.It was shown that activated carbon in our lab had high BET specific surface area and methylene blue decolorizing capacity.Its CH 4 adsorption capacity is approximately five times as much as that of commercial activated carbon.
