Abstract
U.S. governmental agencies are calling for strict environmental regulations on the quality of gasoline. Fluid catalytic cracked naphtha is an important blending component of the gasoline pool. The majority of the sulfur in the gasoline pool comes from these cracked naphthas. Therefore, increased regulations win require the removal of sulfur from fluid catalytic cracked naphtha. The hydrodesulfurization processes used to remove sulfur also saturate olefins and reduce octane number. As the sulfur is removed by hydrogenation, the C6 to CIO olefins become saturated. It has been observed through experimentation that the reactivity of the olefins with hydrogen and the change in octane number depend on the carbon number and type of the olefins. The purpose of this study is to determine the reaction kinetics and develop correlations for C6 to CIO olefin saturation reactions. Data from pilot plant studies at the Texaco Research and Development Lab in Port Arthur, Texas were examined. From the data collected and the correlations that are developed, a more complete understanding of the olefin saturation mechanism in the hydrodesulfurization of FCC naphtha was developed.
