Charcoals were prepared in the laboratory under known carbonization conditions from hard and soft woods. The charcoals were studied by elemental analysis, adsorption of carbon dioxide at 195K, Hg porosimetry, DGA and ignition temperature measurements. The properties of the charcoals were compared an

The behavior of a number of rare earth oxides as catalysts for the oxidation of graphite in air has been investigated by the methods of thermal analysis. Of the oxides studied, only CeO, showed significant activity in accelerating the gasification of graphite by oxygen between 500 and 1000Β°C. Cerium
Carbon catalyses many reactions, mainly oxidation reactions with oxygen and with halogens, e.g. S0,+1/20,-+S03, or CO+CI,-+COCI,. It is known, however, that different carbons behave quite differently in the reduction of oxygen on fuel cell cathodes. Thereforethecatalytic activity of carbons has bee
