Project: YN series catalysts for first stage hydrogenation of pyrolysis gasoline

Award: Third prize of Science and Technology Progress of SINOPEC in 2014

Project introduction:

Pyrolysis gasoline is a by-product of ethylene production, which is refined by two stages selective hydrogenation. In the first stage, diolefins are removed at a lower temperature, and the second stage is used to remove the olefin, sulfur, nitrogen and oxygen compounds at a higher temperature. The refined product is used as the raw material of aromatic hydrocarbon extraction. Yansan branch, BRICI has developed YN series catalysts for first stage hydrogenation of pyrolysis gasoline C4、 C5、 C6-C8、C9-C10 fraction, which has excellent activity for olefin saturation and high activity at low temperature, and its service life is long.
