Coal, char and activated char doped with model vanadium compounds (V 2 O 5 and NH 4 VO 3 ) and petroleum coke ash, PCA, (main metal components: V, Fe and Ni) have been tested as catalytic sorbents for NO reduction without the addition of a reduction reactive. The sorbents prepared have shown to be active for NO reduction at temperatures higher than 350 o C....
Spanish coal, char and activated char doped with model vanadium components (V 2 O 5 and NH 4 VO 3 ) and petroleum coke ash (enriched in V, Fe, and Ni) were prepared and characterized as potential catalytic sorbents for NO x reduction. The phase-mineral and chemical composition, content and behavior (capture, retention, distribution, and redistribution) of transition...
