Validation of effectiveness factor correlations for steam methane reforming in ni-based washcoat catalyst layers using commercial computational fluid dynamics software

HIGHLIGHTS

• What: In this study, the validity of the effectiveness factor correlations proposed for washcoat catalyst layers is investigated by solving the SMR process using the commercial CFD software, ANSYS Fluent . In this study, Dij was determined using the empirical correlation by Fuller et_al as Dij=10 0.00143T pt M ij i j 14, where temperature, T, is in Kelvin and total pressure, pt, is in bar units. In this study, the effective diffusivity of species i in the washcoat catalyst layer, Di,eff, was determined based on the Bosanquet approximation as ϵ/τ Di,eff= 1 Dm,i . . .
