Title: Pd/NaOH-Al2O3 catalyst for NOx abatements
Inventor: YE JIUN-DI
IPC: F01N3/08
Filed: 1998-09-18
Granted: 2000-03-21
Abstract: The Pd/Al2O3 catalyst displayed significant activity towards conversion of NO into N2 and O2 at T > 1050K. On modifying the catalyst with NaOH, required operation temperature may be lowered to 900K. The modified Pd/Al2O3 catalyst may be used in stationary factories and power stations, as well as catalytic converters for abatement of NOx emission. Calorimetric and temperature-programmed-desorption studies revealed that observed catalytic activity at 900K resulted from a formation of interfacial sites which strongly adsorb NO molecules.
