abstract:
The feasibility of adopting an oxy-combustion stage to regenerate a spent catalyst proposed for methane
thermo-catalytic decomposition has been investigated in a laboratory scale bubbling fluidized bed reactor
operated at 800 C and different inlet oxygen concentrations. The efficiency of carbon oxy-combustion
regeneration strategy has been evaluated on the basis of the efficiency of carbon removed from the catalyst
and the performance of regenerated catalyst. The effect of multiple cycles of decomposition and
regeneration steps has been also quantified. Experimental activity confirmed the possibility of producing
a CO2 stream that can be finalized to a sequestration unit but also indicated the requirement of a good
temperature control of catalytic particles.
