The fabrication of carbon solids which have a narrow distribution of pore size and fairly high strength has been made by carbonizing briquettes of grafted carbon black. These briquettes have a large pore volume of about 0.7 ml/g. The carbon black particles are bonded to each other by a carbonized po
The carbon deposited during the catalytic decomposition of CH, over Ni, Co or Fe particles, at temperatures between 500 and 78O"C, was investigated by N, adsorption, TEM and XPS. A much larger amount of carbon was formed on Ni than on Co or Fe. The pore size distribution curves indicate that the car
