SINOx^® plate catalysts consist of catalytically active material composed of titanium dioxide, vanadium oxides and tungsten oxides or molybdenum oxides rolled onto stainless steel mesh. The catalyst plates are integrated into element frames which are installed in a steel module.
Johnson Matthey is proud to announce more than 30 years experience in developing and producing plate catalysts.

The typical application for SINOx^® plate catalysts is the abatement of NOx under high-dust conditions. Examples are plants firing coal, heavy fuel oil and residual oil from refineries as well as industrial high-dust processes and wood fired boilers.

SINOx^® plate catalysts have some advantages compared to conventional honeycomb catalysts. Plate catalysts show minimal dust depositions even under extreme high-dust conditions and also exhibit a high erosion resistance. Additional benefits include low SO₂ conversion rates and low pressure drop. These result in a long service life with high NOx removal rates and minimal operating costs. The most appropriate catalyst type and the required catalyst volume will be individually designed and optimized depending on the exhaust gas conditions. By varying the number of plates per element frame, the pitch can be optimized over a wide range. The plate height will vary depending on operating conditions.
