Method of preparing a coarse-pored formed carbon

摘要

Described is a method for preparing a coarse-pored formed carbon from charcoal dust, charcoal tar and sodium hydroxide solution. These ingredients are mixed, kneaded, shaped and low-tempeature carbonized in as low-oxygen atmosphere as possible at temperatures of 300 to 900 DEG C. The product is further activated with water vapor and/or carbon dioxide at temperature of 700 to 1200 DEG C. In the initial mixture, sodium hydroxide is added in amounts of 5.0 to 15.0 % by weight relative to the amount of charcoal dust.
