Reaction rates specified in VBA. Access VBA from menu: |Tools|Visual Basic Editor|.

Reaction rates specified in VBA. SteamReformHou.pdf describes how to determine the parameter values.

Steam reform (Reaction 1) CH4 + H2O  CO + 3 H2

Water Gas Shift WGS (Reaction 2) CO + H2O  CO2 + H2

Steam reform (Reaction 3) CH4 + 2 H2O  CO2 + 4 H2

In Chemcad, right click on the kinetic reactor, select “Run This UnitOp”. When run is finished, go to menu |Plot|UnitOp Plots|Flug Flow Reactor Profile| Reaction rates specified in VBA Reaction rates specified in “Standard”
