Semi-global intrinsic kinetics for char combustion modeling††Entry 2 has also been referred to as “Langmuir kinetics.” The present paper adopts common chemical engineering usage, in which the designation “Langmuir” is applied to the equilibrium adsorption isotherm, and when the isotherm is applied within the derivation of a kinetic law for a heterogeneous reaction the result is referred to as a Langmuir–Hinshelwood (LH) kinetic law, or Langmuir–Hinshelwood–Hougen–Watson (LHHW) kinetic law. There are many LH kinetic forms—entry 2 is valid for the special case of no surface reaction between adsorbed species.
