Abstract: GARDES technology developed by PetroChina Petroleum and Petrochemical Research Institute and China University of Petroleum (Beijing) was adopted in the 1.1 Mt/a catalytic cracking gasoline hydrogenation unit of PetroChina Sichuan Petrochemical co. Ltd，using catalytic cracking gasoline as the raw material to produce motor gasoline blending component in compliant with GB 17930—2016. The calibration results indicated that the mixed gasoline products with the mass fraction of sulfur of 7.1 μg/g can be obtained from the raw material of FCC gasoline with the mass fraction of sulfur of 69.6 μg/g，volume fraction of olefin of 30.3%，volume fraction of aromatics of 18.4%，and the octane number（RON） of 91.7. The loss of octane number（RON）is 0.5 unit. The yield of mixed gasoline is 99.41%, which is better than the control index, and the integrated energy consumption is slightly higher than the control index.

Key words: catalytic cracking gasoline, hydrogenation, GARDES
