Los Angeles-ACAT Global, touting its new catalytic converter technology, now claims a breakthrough that will be a strong competitor for urea-based diesel exhaust fluid. ACAT has introduced what it calls markedly advanced stainless steel alloy foil catalytic converter substrate cores for eliminating NOx and other pollutants without the need for a urea additive. ACAT says the ACAT Non-Urea Syngas-Based Diesel Emission Reduction System enables manufacturers to reduce NOx to nitrogen gas without requiring a separate containment and injection urea dosing sub-system. “The times they are a changin’,” ACAT spokeswoman Leisa Cuddy told Green Markets. “Urea adds a huge infrastructure load that is far from green. It is our understanding that the addition of urea is a band-aid solution to an enormous environmental problem.” ACAT reports that no secondary exhaust sub-system is required with its approach because the metal monoliths used in diesel catalytic converters rely on high thermal conductivity instead of chemical reaction in reducing exhaust gas NOx. In addition to ACAT’s monolith cores, the retrofit kits feature synthesis gas (syngas) generators and diesel particulate filters.
