    • PURPOSE: Disclosed is a simultaneous removal method of nitric oxides (NOx) and dioxin from flue gas using chromium oxide catalyst supported titanium dioxide. CONSTITUTION: The method is composed of several steps of a simultaneous removal process of nitric oxides and dioxin: an ammonia injection step, a flue gas feed step into a reactor installed with 5-40wt% chromium oxide supported on titanium oxide, operating at 250-450deg.C, and a simultaneous removal step of NOx and dioxin. In addition, the used catalyst prefers a +6 oxidation state to a +3 oxidation state of chromium species and the structure of the catalyst may be selected all kinds of form such as a fine powder, a pellet, a coated filter or honeycomb reactor or an extruded honeycomb structure. Instead of ammonia as reductant gas for controlling nitric oxide gas, urea compound may be used with a suitable concentration.
    • 目的:公开了使用氧化铬催化剂负载的二氧化钛同时从烟道气中除去一氧化氮(NOx)和二恶英。 方法:该方法由一氧化氮和二恶英的同时去除过程的几个步骤组成:氨注入步骤,烟道气进料步骤,安装在负载在氧化钛上的5-40重量%氧化铬的反应器中, 450℃,以及NOx和二恶英的同时除去步骤。 此外,所使用的催化剂优选+6氧化态到铬物质的+3氧化态,并且催化剂的结构可以选择各种形式,例如细粉,颗粒,涂布过滤器或蜂窝反应器,或 挤压蜂窝结构。 代替氨作为用于控制一氧化氮气体的还原气体,可以以合适的浓度使用尿素化合物。
