Kinetic Models and Networks

Mechanistic and experimental studies generally result in the creation of a kinetic network that quantitatively describes the path a particular reactant takes. Given the complexity of the reforming reactions and the number of species involved, many researchers have taken a lumped approach towards describing the kinetics. In a lumped approach, many different molecules are placed into a single group or lump. The reaction kinetics then assumes that all species in a lump behave identically. Recently, some researchers have presented models that involve hundreds of reaction species and thousands of reactions [16,18], However, there is little published information about these complex kinetic models validated against industrial operation. 

This model has 20 lumps and 53 reactions. Eq. (5.1) shows the basic form for each rate expression
