Mechanism and Kinetics of Steam Reforming

Methane Reforming.—Several of the kinetic equations in Table 4 relating to CH4 reforming include a term (1 — K jK), where K is the equilibrium constant for the reforming reaction, e.g. (5) or (6), and K is pco. Ph IPch. Ph o for example for reaction (5), pco, etc. being the actual partial pressures of the gaseous components. The term is important under conditions near equilibrium because it takes into account the back reaction, the rate of which increases as equilibrium
