Abstract: The domestic demand for ethylene has been on the rise in recent years. Wide application of C4, C5 and C9 becomes a focus of attention. The LY-2005 high-nickel catalyst, developed by PetroChina Lanzhou Petrochemical Research Center, is suitable for deeplysaturated hydrogenation of medium to low distillate oil, such as C4, C5 and C9. In the development process of the catalyst, natural largepore mineral auxiliary pore-making technology is innovatively used to maximize olefin saturation activity of the catalyst and improve antisulfur properties of the catalyst by means of introducing electronic additive technology. This catalyst has three process characteristics. First of all, it is a high-nickel catalyst with cost-effectiveness and stronger anti-impurity ability as compared to precious metal catalysts. Secondly, it is of low hydrogenation reaction temperature and reaction can take place at the room temperature. Thirdly, it has good hydrogenation stability and activity with an industrial operational period of more than five years, making the alkene content of hydrogenation products less than 0. 1 percent.
