Abstract
A novel process effective for the removal of organic sulfur compounds, organic nitrogen compounds and light olefins from liquid hydrocarbons is disclosed. The process more specifically addresses the removal of these contaminants from aromatic compounds including benzene and toluene and from naphtha. The liquid hydrocarbons are contacted with a blend of at least one metal oxide and an acidic zeolite. Preferably, the metal oxide comprises nickel oxide and molybdenum oxide and the acidic zeolite is acidic stabilized zeolite Y. This blend has a significant capacity for adsorption of impurities and can be regenerated by oxidative treatment.
