Basic study of the development of new technology for high performance activation

Abstract

The effectiveness of a new technology for the efficient manufacture of activated carbon, which is based on alkali activation and is able to recover the consumed alkali activator by oxidants at the reaction site, has been demonstrated. The in situ regeneration of the consumed alkali activator is made by intermittently supplying water vapor to the reaction site. The amount of the alkali required is reduced to about 10% of that needed by conventional methods and the yield of activated carbon is improved by nearly 60% using the activation of coconut shell char as an example.
