Ammonia-Related Catalysts
What are "Ammonia-related Catalysts"?
These precious metal catalysts oxidize and remove low-concentration ammonia emitted from ammonia cracking and other applications, which are attracting attention as a clean energy source.As ammonia is increasingly used as a hydrogen carrier and fuel, this catalyst lineup supports next-generation energy technologies by contributing to efficient reaction promotion and reduced emissions of harmful substances.
TANAKA's Ammonia (NH3) - Related Catalysts
Ammonia (NH3), which is expected to serve as a hydrogen carrier and a zero-emission fuel that, like hydrogen, does not emit CO2 during combustion. We offer ammonia reforming catalysts for decomposing ammonia to generate hydrogen, as well as catalysts for suppressing and decomposing nitrogen oxides (NOx) and nitrous oxide (N2O) in ammonia-containing exhaust gas.
