Abstract: Catalytic reforming is a major refinery process for upgrading low-octane naphtha to high-octane gasoline and also for supplying raw-materials to chemical and textile industries etc. Many articles have been published on the improvement of the process for better and more yields, and models of reac-tion kinetics have been developed for its optimization, but a general review of the optimum operating conditions is lacking. Based on chemical reaction engineering integrated with the actual practice in the chemical works, the author writes at great length about the choice of reaction temperature pressure and molecular ratio for optimizing the process.
