    摘要： A process for the denitration of combustion exhaust gas from combustion equipment by passing the exhaust gas through an ammonia reduction denitrator, comprises providing a bypass having a low-temperature denitrator installed therein; while the temperature of the exhaust gas is not high enough to allow the ammonia reduction denitrator to function properly, as encountered immediately after starting the combustion equipment, passing the exhaust gas through the bypass to perform the denitration thereof by means of the low-temperature denitrator; when the ammonia reduction denitrator has come to function properly, closing the bypass to perform the denitration of the exhaust gas by means of the ammonia reduction denitrator; and regenerating a catalyst within said low-temperature denitrator while the by-pass is closed.

    摘要： An active carbon for use in the treatment of exhaust gas can be obtained by heat-treating a starting active carbon fiber derived from polyacrylonitrile, pitch or the like or a starting particulate active carbon in a non-oxidizing atmosphere. The heat-treating temperature is preferably in the range of 600 to 1,200 ° C. for use in the desulfurization of exhaust gas, and in range of 600 to 1,000° C. for use in the denitration of exhaust gas. By using the resulting heat-treated active carbon for the purpose of desulfurization, the sulfur oxide concentration in exhaust gas can be reduced to 5 ppm or below. Moreover, by using the heat-treated active carbon in combination with conventional denitration based on selective catalytic reduction, the nitrogen oxide concentration in exhaust gas can be reduced to 1 ppm or below.
