Abstract
The present invention relates to specific activated carbon materials including from 1 to 5% by weight of nitrogen, from 3 to 30% by weight of oxygen and from 40 to 95% by weight of carbon, and having an average pore radius of from 15 to 30 .ANG., with the proviso that mesopores occupy at least 50% by volume based on the total pore volume, and also relates a process for the preparation thereof, and to the use thereof as catalysts.
Claims3
Activated carbon materials comprising from 1 to 5% by weight of nitrogen, from 3 to 30% by weight oxygen and from 70 to 95% by weight carbon, and having an average pore radius of from 15 to 30 .ANG., with the proviso that mesopores occupy at least 50% by volume based on the total pore volume, and wherein said activated carbon materials are produced by subjecting protein-containing sludge or waste materials which comprise microbial proteins or biologically activated sludge to carbonization and activation treatments, followed by an acid treatment to remove impurities and a heat treatment at 400.degree.-1100.degree. C. under an inert gas or a reducing gas atmosphere to enhance activity.
