ABSTRACT
In Chapter 3 of the first edition of this book[1] the hydrocarbon reactions occurring during naphtha reforming were reviewed. The most important reactions (from most rapid to slowest: dehydrogenation of cyclohexanes, dehydroisomerization of alkylcyclopentanes, dehydrogenation of paraffins, isomerization of paraffins, dehydrocyclization of paraffins, hydrocracking, hydrogenolysis, and coke deposition) were analyzed individually. The thermodynamics, kinetics, and mechanisms of each reaction were studied, and the influence of operational parameters on the activity, selectivity, and stability of the reactions and the reaction models for naphtha reforming were used to conclude which operational conditions are the most convenient. As the most important reactions of naphtha reforming occur through bifunctional catalysis, the chemistry of the bifunctional metal-acid catalyst is emphasized in this chapter.
