Revisiting the steady states of NO/O₂/C₃H₆ on monolithic Pt/BaO/Al₂O₃ using bifurcation analysis

Abstract

in Wiley Online Library (wileyonlinelibrary.com) While NOx storage and reduction is periodically operated, steady-state studies have been widely carried out to investigate the involved reaction mechanisms and effects of operating parameters. Due to the complex reaction chemistry and its coupling with transport phenomena, multiplicity may exist. A steady-state monolith reactor model accounting for microkinetics and reaction heat effects was proposed in this study to avoid the evaluation of enthalpies of microreaction steps. Three simplified versions of the monolith model were developed based on various assumptions of the axial gradients. Steady-state behaviors of NO/O 2 /C 3 H 6 system were investigated. A predictor-corrector (PC) continuation method that does not require explicit evaluation of Jacobian Matrix was developed to solve the nonlinear system with a variable parameter of feed temperature. Model predictions were compared with experimental results.

Fast and highly efficient SO2 capture by TMG immobilized on hierarchical micro–meso–macroporous AlPO-5/cordierite honeycomb ceramic materials

“…25 They have been widely applied to carry out catalytic reactions, especially for vehicle exhaust treatments. 26,27 Another interesting problem would be whether honeycomb skeletons can be loaded with micro-mesoporous zeolites containing TMG as the washcoat.…”
