For over a century, internal combustion engines have powered transportation and played a key role in emergency backup power and remote power generation. Until recently these engines have run exclusively on liquid fuels.
This has changed due to the current abundance of natural gas. Advancements in materials and design allow natural gas engines to produce up to 18 megawatts of power, and when used in parallel, they can sometimes compete with larger gas turbines for base load power generation.
Umicore's DNX® and DNO® catalysts play an important role in reducing harmful emissions such as NOx, CO and VOC from these engine sources. The unique corrugated substrate allows for a large overall catalyst pitch size, compared to extruded type catalyst, which keeps overall backpressure low while still keeping a small catalyst footprint. In biogas applications, rife with siloxane poisons known to dramatically reduce overall catalyst activity, Umicore's DNX® and DNO® catalysts have proven ultra-high tolerance levels to poisons while maintaining excellent catalytic activity.
