Essentially, thus ends the exposition of Kmak. Now the reader will understand that this still leaves us a long way from direct application of the methodology developed earlier. What would remain to be specified? Essentially we need to do three things: (1) Identify the nature of coke precursors. (2) Determine the relationship between coke content and the fraction of active sites a [which is related to L in Eq. (2-72)]. (3) Determine the dependence of the rehydrogenation rate on pHl and also determine whether the reverse rate £%C-HC has the same impact as the forward rate on the active fraction a.
