摘要：

The reductive removal of nitric oxide from flue gases by reaction with polyacrylonitrile-based active carbon fibres (PAN-ACF) activated with sulphuric acid has been studied at 423-632 K, using a circulating flow reactor. Nitric oxide (0. 67 mmol) was completely removed via reduction with 1 g activated carbon under optimum conditions in 210 and 60 min at 423 and 623 K, respectively. N//2 was formed as nitric oxide was removed. Some oxygen remained on the carbon surface at 423 K, but was desorbed as CO or carbon dioxide on subsequent heating to 623 K. The bimolecular reaction of NO reduction over PAN-ACF, and the possible active sites of oxygen surface groups are discussed in the light of a kinetic study.
