- Abstract
- Novel monolithic catalysts for the high-temperature combustion of methane have been developed
with a dual-site nature, to combine low and high temperature activity within a single system
and widen its operating range. Such catalysts are based on strongly interacting Pd and LaMnO3
active phases supported onto La/ç-alumina and applied as a thick washcoat on ceramic
honeycombs. Optimization of the preparation procedure and catalyst characterization were
performed with respect to the effects of Pd deposition method, catalyst activation strategy, and
thermal history in comparison with previously developed catalysts based only on supported
perovskite. Extensive methane combustion tests (steady state and transient) were run under
both isothermal and autothermal lean premixed conditions in order to study intrinsic oxidation
activity, light-off behavior, and real life performance in the middle to high temperature range.
Experimental evidence is presented for improved activity, stability, and durability of the catalytic
system, and for a self-regenerative behavior of Pd active sites through reversible interaction
with perovskite lattice. Implications of novel combined catalyst functionalities are addressed
with respect to operation of a fully catalytic burner. (literal)
