Estimation of concentration and temperature profiles for methane-steam reforming reaction in a porous catalyst

Non-isothermal reaction-diffusion systems with thermodynamically coupled heat and mass transfer

“…Modeling of spatio-temporal evolution may serve as a powerful complementary tool to experimental non-isothermal reaction-diffusion (RD) systems within a porous catalyst particle and membrane (Weisz and Hicks, 1962, Hlavecek et al, 1969, Aris, 1975, Froment and Bischoff, 1979, Dekker et al, 1995, Pan and Zhu, 1998, Levent et al, 1998, Levent, 2001, Kafarov et al, 1998and Burghardt and Berezowski, 2003Selegny et al, 1995a andSelegny et al, 1995b). Non-isothermal RD systems represent thermodynamically and mathematically coupled transport and chemical processes, and need a through analysis, as they may evolve multiple steady states with unique dynamic phenomena (Burghardt and Berezowski, 2003).…”

Kinetics Analysis and Process Simulation for Sorption-Enhanced Steam Methane Reforming

“…The activation energy of the set of elementary steps for SMR process was obtained by Yang et al [12] on the basis of bond order conservation Morse potential (BOC-MP) and the pre-exponential factors of the rate expressions of these elementary steps were then estimated according to the reported ranges in literature. Avetisov et al [15] developed a microkinetic model and the results showed that the rate of methane reforming in a forward direction was caused by their influence on reversibility of a step and the microkinetic model fairly well described both published and their own experimental data.…”

Autothermal reforming of methane gas—Modelling and experimental validation

“…In addition, to account for the effect of gas diffusion into (and out of) the catalyst, the effectiveness factor, Z eff , is included in the mathematical model which is determined by [16][17][18] …”
