PROCESS OF REGENERATING CATALYST FOR DENITRATION

摘要

The present invention relates to a method for reusing a material through a catalyst applied and used in SCR which is a facility for reducing nitrogen oxides in overall industrial processes including coal thermal power plants, wherein a carrier is TiO_2, and a catalyst active component is V_2O_5 and WO_3. A particular level or less (each 2% or less) of Si and Al is included as another catalyst ingredient in the components. The catalyst corresponds to 20-40 wt% of Ti components, 0.1-5 wt% of V components, and 1-10 wt% of W components, and the catalyst shape may be a honeycomb shape, a plate shape, a wave shape, or wave-honeycomb shape. In the present invention, physical regeneration is firstly performed on a denitrated waste catalyst having high chemical poisoning, and active ingredients are added, so that target denitrating efficiency can be achieved. A dipping process is performed without a separate drying process, so that treating time can be reduced.
