The research institute and the catalyst plant of PetroChina Lanzhou Petrochemical Company have successfully developed LBO-A high-octane olefin-reducing co-catalyst, which has been tried in the commercial FCC units in PetroChina Harbin Petrochemical Company and PetroChina Lanzhou Petrochemical Company. The commercial operation demonstrates that, when the olefin-reducing catalyst is added with this co-catalyst, the olefin in FCC gasoline is reduced by 3% -5% , octane number is enhanced, little change is observed in product distribution and reaction performance of olefin-reducing catalyst is improved.
