TREATMENT TO RECOVER SULFURIC ACID-ACTIVATED ACTIVATED CARBON FIBER AND TREATMENT TO REMOVE NO FROM NO-CONTAINING GAS

摘要

PURPOSE:To reactivate a sulfuric acid-activated ACF having decreased NH3 adsorptivity at room temp. to about 100 deg.C, lower than a conventional method, and to remove NO from NO-contg. gas. CONSTITUTION:This recovering method for sulfuric acid-activated activated carbon fiber features in that a NO-contg. gas is brought into contact with the sulfuric acid-activated activated carbon fiber adsorbing NH3 to reactivate the carbon fiber. Also, this invention relates to the method of removing NO from NO-contg. gas. by the treatment above described.
