ACTIVE CARBON FIBER CATALYST FOR REDUCING NITROGEN MONOXIDE WITH AMMONIA AND NITROGEN MONOXIDE REMOVING PROCESS FOR NITROGEN MONOXIDE CONTAINING GAS

摘要

PURPOSE:To prepare an active carbon fiber catalyst for reducing nitrogen with ammonia which can remove effectively nitrogen monoxide in atmosphere. CONSTITUTION:1. An active carbon fiber catalyst for reducing nitrogen monoxide with ammonia is prepared by baking active carbon fiber in non-oxidizing atmosphere at 600-1200 deg.C and then subjecting to sulfuric acid activation treatment. 2. Nitrogen monoxide in gas is removed by bringing ammonia gas and nitrogen monoxide containing gas into contact with the active fiber catalyst for reducing nitrogen monoxide with ammonia in the nitrogen monoxide removing process for a nitrogen monoxide containing gas. 3. Nitrogen monoxide in the gas is removed by making ammonia adsorbed on the active carbon fiber catalyst for reducing nitrogen monoxide with ammonia and then bringing the same into contact with the nitrogen monoxide containing gas in the nitrogen monoxide removing process for nitrogen monoxide containing gas.
