Mercury Mitigation Strategy Through The Co-Benefit Of Mercury Oxidation With SCR Catalyst
An SCR Can Provide Mercury Removal Co-Benefits
With today’s emissions requirements you need a catalyst and catalyst supplier that can exceed your needs for NOx removal. Mitsubishi Hitachi Power Systems is the prime supplier of plate-type catalyst, and our plate technology has now operated successfully in over 750 units worldwide, with over 350 units supplied to coal fired units. Our catalyst is manufactured and designed by our affiliate company Babcock-Hitachi K.K. (BHK) in Akitsu, Japan, one of the original co-developers of Titanium Oxide based catalyst in the 1970’s. Our vast experience and knowledge makes us the most ideal solutions partner.
Our plate technology utilizes catalyst elements manufactured with active catalyst ingredients on a titanium dioxide matrix supported on a stainless steel mesh substrate. Multiple catalyst plate elements are then assembled in a steel unit case and these catalyst units are assembled into a welded steel frame to form a catalyst module for handling in the field. The catalyst modules are designed to be loaded through an access door located at the side of the SCR reactor.
Our plate catalyst is the optimum choice for your catalyst needs for Anthracite and Bituminous coals to Powder River Basin, Lignite, and Petroleum Coke. Hitachi’s success and innovation is everything you would expect from the original developer and supplier of DeNOx catalyst.

TRAC® – TRiple Action Catalyst
Mitsubishi Hitachi Power Systems offers the latest enhancement of NOx Reduction Catalyst for Selective Catalytic Reduction Systems which has been developed to increase the oxidation of elemental mercury.
This new catalyst called TRAC® (TRiple Action Catalyst) increases the oxidation of mercury with minimal chlorine levels. It can be used on Bituminous and Sub-Bituminous (PRB) fuels. Not only does this catalyst reduce NOx and oxidize mercury, it also minimizes the conversion of SO2 to SO3. Thereby the phrase, “Triple Action.”
Depending on the application, this catalyst can eliminate or minimize the need for other mercury oxidation agents such as halogens and activated carbon.
