A series of modified carbonaceous materials has been obtained via nitrogenation, oxidation and thermal treatment of peat-based activated carbons with the use of microwave heating. In order to obtain materials characterised by diverse functional groups content, both in terms of the type and quantity, the starting material was subjected to four different treatment: (1) oxidation with nitric acid followed...
The effect of oxidation by 20% nitric acid on the properties and performance of active carbons enriched with nitrogen by means of the reaction with urea in the presence of air has been studied. The study has been made on demineralised orthocoking coal and the carbonisates obtained from it at 600 or 700°C, subjected to the processes of nitrogenation, oxidation and activation with KOH in different sequences...
