Webb13 juni 2024 · Moreover, a modified Langmuir-Hinshelwood (L-H) kinetic model considering all detected intermediates was developed. A good agreement between experimental and estimated results was achieved. This model can be useful for scaling-up purposes more accurately as its considering the intermediates formed, which has a …
WebbMB using Zn/SBA-15 was modeled by the Langmuir-Hinshelwood model [15]. This model assumes a direct correlation between the occupation rate of sorption sites with the number of unoccupied sites.
