Selection of Kinetic Data for Modeling

The selection of the heterogeneous kinetics is limited to surface-related extended Arrhenius expressions because of the universal and easy application in 

Sergeant and Smith [4,30] Bituminous char 800 1700 85.6 1 2.903E-03 0 7.542E-01 1 

Smith and Tyler [4,32] Brown coal char 630 1812 136.3 0 1.320E-01 0 1.320E+02 0 

Mayers [4,25,36] Utah bituminous, Wyoming subbituminous 600 2600 146.9 1 2.883E-03 0 1.330 1 

As a result, three sets of surface-related pressure-based rate data are recommended for modeling. They have been adopted from several suggestions [4,10,28]. The sets display suitable behavior (reaction rate at constant temperature O2 H2O CO2) and proved their suitability for modeling. Further details are provided elsewhere [41]. The data are provided in terms of extended Arrhenius expressions according to Equation (5.26) and are shown in Table 5.6.
