Catalysts for hydrogenation of pyrolysis gasoline
The hydrofining process of pyrolysis gasoline is divided into two stages, and corresponding catalysts are also classified into two kinds. The first stage hydrogenation catalyst is used to remove diolefins in pyrolysis gasoline, and the second stage hydrogenation catalyst is used to remove the olefin, sulfur, nitrogen and oxygen compounds etc.
Yanshan branch, BRICI started the research of catalysts for hydrogenation of pyrolysis gasoline in 1980s. The catalysts have been successfully applied many times.
