A mass balance simulation model for sorption in a packed bed reactor was developed. All of the terms in the model, consisting of constants of the porous media, and functions, were evaluated by independent laboratory studies. The kinetic term was determined in Part I. Two numerical schemes (an explicit scheme and an implicit scheme respectively) with corresponding computer programs were developed and made operational. They were not tested against laboratory column results due to long times necessary on the computer and corresponding high costs. Laboratory testing consisted of measuring column profiles for six different packed columns at different flow rates and feed concentrations and for two sorbents, Dowex 50 resin and Filtrasorb 200 activated carbon. Further Kinetic studies were also conducted on the problem of whether sorbate delivery rate by bulk convection is rate controlling. This was termed “transport kinetics” and comprised a part of the simulations model.
