Kinetics of Redox Half-Cycles on Bi2O3 for the Selective Catalytic Combustion of Hydrogen

Matthew Jacob,
Huy Nguyen,
Matthew Neurock
et al.

Abstract: The kinetics of selective hydrogen combustion (SHC) in mixtures with hydrocarbons on Bi 2 O 3 in the absence of gasphase O 2 , process conditions mimicking chemical looping processes and reduction half-cycles in Mars−van Krevelen mechanisms typical in hydrocarbon partial oxidation, are assessed by employing metrics for the rate and selectivity which account for the stoichiometric nature of oxygen abstraction in SHC. These assessments consider the kinetic relevance of surface reactions and bulk lattice oxygen d… Show more
