Johnson Matthey Stationary Emissions Control

Gas Turbines

Johnson Matthey pioneered oxidation catalyst for gas turbines in the 1970s. Since then, oxidation catalysts have been installed in some of the most environmentally challenging applications, consistently providing greater than 90% destruction of CO, VOCs, formaldehyde and other toxic compounds. Our core expertise in catalysts has allowed us to stay at the cutting edge of new catalyst development meeting the challenges of ever increasing regulatory requirements.

Our oxidation catalysts are formulated with Platinum Group Metals (PGMs) to achieve maximum conversion of pollutants at turbine temperatures, whether it is a simple or combined cycle unit. Our high activity catalyst plus flow-through-metal monolith design delivers the smallest catalyst package and the lowest backpressure in the industry. We have thousands of cubic feet of oxidation catalyst installed throughout the world in some of the most environmentally challenging applications. This enhanced catalyst was designed specifically for gas turbines. Our unique substrate foil combined with an optimized catalyst coating, improves the mixing of exhaust gases, and increases catalyst activity. This level of pollutant destruction, with less catalyst volume, results in lower backpressure and sizeable savings over the life of the turbine.

Johnson Matthey recently developed a compact extruded ceramic honeycomb SCR catalyst that provides high NOx conversion performance in a smaller package. It is a low back pressure design giving the turbine owner/operator greater flexibility. The SCR catalyst itself is the most robust available on the market today providing the widest operating temperature window for a variety of turbine operating conditions. Johnson Matthey's SCR catalyst modules are ideally suited for new applications or they can be installed in exiting housings.
