Catalysts that have potential in simultaneous removal of H2S and NH3 decomp
osition were developed. The monolith supports of high surface area and acce
ptable mechanical strength based on titania and silica-alumina precursors w
ere prepared and tested. Preparation routine and composition of Mn, Fe and
Cu oxides supported honeycomb catalysts have been optimized. Impregnated an
d washcoated monolith catalysts were tested in ammonia high-temperature dec
omposition. (C) 2001 Elsevier Science B.V. All rights reserved.
