The present application relates to a process for treating gasoline, comprising the steps of: splitting a gasoline feedstock into a light gasoline fraction and a heavy gasoline fraction; optionally, subjecting the resulting light gasoline fraction to etherification to obtain an etherified oil; contacting the heavy gasoline fraction with a mixed catalyst and subjecting it to desulfurization and aromatization in the presence of hydrogen to obtain a heavy gasoline product; wherein the mixed catalyst comprises an adsorption desulfurization catalyst and an aromatization catalyst. The process of the present application is capable of reducing the sulfur and olefin content of gasoline and at the same time increasing the octane number of the gasoline while maintaining a high yield of gasoline.

A process is disclosed for shifting the product of a hydrocracker in a hydrocarbon refinery back and forth from a more naphtha focused product slate to a more diesel focused product slate to take advantage of price and demand shifts between gasoline and diesel by using a naphtha selective catalyst and temporarily passivating the catalyst with a basic material such as ammonia in the hydrocracker. The ammonia passivates the acid catalyst sites on the catalyst and produces more total liquids and more diesel with attractive cold flow and pour point properties for a temporary period. When implemented in a temporary manner and the flow of ammonia is suspended the hydrocracker product slate returns to a more gasoline focused slate.
