What is catalytic hydrogenation?
Catalytic hydrogenation refers to the process in which petroleum fractions can be hydrogenated with the help of the hydrorefining catalysts. Catalytic hydrogenation can be classified into three categories.
1) Hydrorefining. The feedstocks can be from gasoline to crude oil. The process purpose is to remove sulfur, nitrogen and oxygen contained in their compounds to improve the quality of the oil products. As for the oil products from secondary processes olefins can be saturated and the aromatics can be hydrogenated. Heavy metals acting as poisons can be removed from the catalytic reforming stock. Therefore the catalytic reforming catalysts can be protected from being poisoned. The hydrorefined oil products are not only good in quality, but also high in yields.
2) Hydrocracking process. Most of heavy distillate oils including FCC recycle oil and coker distillates are used as feedstocks. The final products from this process include gasoline, jet fuel, diesel oil to isopentane and isohexane.
3) Hydrorefining process of lube oil can be used instead of the solvent refining and clay treatment of lube oils.
