In present work, we discovered a high-performance monolithic
PdNi(alloy)/Ni-foam catalyst for the catalytic CBM deoxygenation
and demonstrated its facile fabrication engineered from microto
macro-scales via galvanic exchange reaction deposition (called
“galvanic deposition” hereafter) method [28–32,34,35] followed
by in-situ reaction-induced Pd-Ni alloying in the real reaction
stream. The effects of the catalyst preparation and reaction conditions
on the catalyst performance were investigated, as well
as its permeability and heat conductivity, the oscillatory behavior
at different temperatures, and the stability. These experiment
results indicated that this new approach provided a combination
of enhanced heat transfer, desired mechanical robustness, and
excellent low-temperature activity/selectivity and reaction stability
with oscillation suppression in the CBM deoxygenation process
via catalytic combustion. Moreover, the characterization results
clearly identified the formation of PdNi alloy on the Ni-foamand the
formed PdNi alloy was contributed to the low-temperature activity
