The surface chemistry and the porous texture of activated carbons prepared from a charred product (C Jex -600), which was obtained from rockrose (Cistus ladaniferus, L.) extracted previously into petroleum ether, were studied. Activated carbons were prepared by heating C Jex -600 between 350 and 850°C in air to 40% burnoff. Methods of chemical analysis and FTIR...
The char produced from a subbituminous coal is a cheap and effective adsorbent to remove nitrogen oxides (NO x ) from flue gas. This paper addresses the NO x adsorption on char in the presence of oxygen and moisture since there are both water vapor and oxygen present in flue gas. The experimental results of this study show that nitric oxide (NO) is catalytically oxidized to nitrogen...
Microwave energy was used to regenerate the NO x saturated char samples. It was found that the temperature of gas produced from microwave regenerations was close to the room temperature, and CO and CO 2 were released approximately 10 seconds after microwave energy was applied. These observations suggest that the sites occupied by NO x may absorb more microwave energy than pure...
