Catalytic Combustion System (CCS), Direct Flame Incinerator (DFI), and Regenerative Thermal Oxidizer (RTO) are well known as combustion methods to treat exhaust gases. In contrast, active carbon adsorption, solvent recovery, chemical washing, biological deodorizing, etc. are represented as non-combustion methods.

A catalytic combustion system can be applicable to any exhaust gases by taking measures against catalyst poisons. Moreover CCS can be applicable to odor treatment without generating thermal NOx or CO. N-U offers various catalysts for CCS with high performance and low-temperature activity.
