Product Introduction
The olefin saturated hydrogenation catalyst not only has a high alkane single-pass conversion rate and olefin selectivity, but also has a very stable hydrogenation performance after repeated regenerations. It can be used in fixed bed, moving bed and fluidized bed reactors.
Especially suitable for hydrogenation saturation of gasoline from oligomerization of light olefins such as ethylene, propylene and butene.
Olefins saturated hydrogenation is to saturate the double bonds of olefins into single bonds and turn them into alkanes. Olefin saturated hydrogenation technology is an effective way to rationally utilize low-value saturated olefins to produce high value-added corresponding alkanes. The olefin saturated hydrogenation catalyst with molybdenum and nickel as active components is used in the process of hydrodesulfurization and hydrodenitrogenation of vacuum gasoline, and the process is accompanied by cracking reaction.
Characteristics of olefin saturated hydrogenation (catalysis) reaction:
① The conversion rate is close to 100%, and the product is easy to purify;
② The difficulty of hydrogenation reaction is related to the structure of olefins;
③ Under normal circumstances, olefin saturated hydrogenation reaction products are mainly cis products, so it is called cis hydrogenation;
④ The role of the olefin saturated hydrogenation catalyst is to change the reaction pathway and reduce the activation energy of the reaction;
⑤ The saturated hydrogenation reaction of olefins has important industrial applications: to obtain hydrogenated gasoline and improve the quality of oil products;
⑥The hydrogenation reaction is an exothermic reaction.

The olefins saturated hydrogenation reaction is a strong endothermic reaction, which is limited by thermodynamic equilibrium and requires a higher reaction temperature. This is beneficial to the improvement of olefin selectivity.
Both hydrodesulfurization reaction and olefin hydrosaturation reaction are important chemical reactions in FCCN hydrofinishing process. Both olefin saturation rate and desulfurization rate increase with the increase of reaction temperature. When the reaction temperature is higher, the olefin saturation rate changes more obviously; when the reaction temperature is lower, the desulfurization rate changes greatly with the reaction temperature.
Under the same conditions, the saturation reaction rate of diolefins is the highest, followed by normal olefins and isoolefins, and the saturation reaction rate of cycloolefins is the lowest.
