Abstract: With the decline of diesel/gasoline ratio，SINOPEC Anqing Company adopted new technologies and better processing routes for FCC light cycle oil. The RLG technology processing route was selected and optimized by comparing various processes such as hydrofining depth，hydrotreating VGO mixed with LCO，hydrocracking of VR mixed with LCO，LTAG and RLG. The RLG process can produce more gasoline and reduce the diesel yield. The combination of RLG with the LTAG technology can further reduce the ratio of diesel/gasoline and obtain better economic benefit.

Key words: light cycle oil, mixed hydrogenation process, LTAG, RLG
