This study has reviewed the current state of knowledge for upgrading the denitrification process to remove nitrogen oxides in the exhaust gas, which is known as a source of ultra-fine dust. In order to upgrade the denitrification process, the hybrid-type denitrification has been considered where the selective non-catalytic reduction (SNCR) is combined with the selective catalytic reduction (SCR) process at a high temperature. Although SCR technology is a mature technology with high denitrification efficiency, it is difficult to be applied to a small-scale process when considering the capital and operating costs for reducing ultra-fine dust. Therefore, it is necessary to minimize the operating cost by applying denitrification technology to the dust collection process, and the development of technology to use a catalyst in the filter bag is required. However, in order to activate the denitrification catalyst in the filter bag, there are some technical problems to be solved: the optimization of the catalyst composition that can be operated at low temperature and the prevention of fall-off of the catalyst in the removing step of collected dust on the filter by high-pressure backwashing. If these technical issues are solved, the hybrid denitrification process can be applied to the industry for the advancement of denitrification technology.
