Model discrimination by reaction dynamics of steam reforming of methanol with CO formation

Comparative simulation studies of the kinetics of steam reforming of methanol were carried out at 473-573 K and steam/methanol molar feed ratio (1-1.4) using the recently proposed and widely accepted rate models including CO formation. The models considered were the Peppley model, which is based on...
