Latest Patents

Douglas S Diez holds a patent for a hydrocarbon upgrading process. This process involves producing low sulfur gasoline with a relatively high octane number from a catalytically cracked, sulfur-containing naphtha. The method includes hydrodesulfurization followed by treatment over an acidic catalyst under endothermic conditions in a second reaction zone. Heat is added to this endothermic reaction zone to initiate and maintain octane restoring reactions. The preferred acidic catalyst is an intermediate pore size zeolite, such as ZSM-5. This treatment restores the octane loss that occurs during hydrogenative treatment, resulting in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. The addition of heat in the second zone prolongs the hydrodesulfurization catalyst life by allowing a lower reactor temperature and maximizes octane increase.
