Abstract: FCC diesel contains 60%～80% aromatics，which leads to its high density and low cetane number，so it is difficult to produce clean diesel through routine hydro-upgrading technology from FCC diesel. This paper mainly introduces a novel FD2G technology，developed by Fushun research institute of petroleum and petrochemicals，which is applied to produce light aromatics from FCC diesel containing aromatics through high efficient hydro-conversion. The optimized combination of hydroprocessing catalyst and process technology adopted by FD2G achieves the selective hydrogenation of aromatics. It can be used to convert the heavy aromatics in FCC diesel into light aromatics with high added-value，which provides an economic and effective route for processing FCC diesel containing high aromatics. The results showed that applying FD2G technology developed by SINOPEC to process FCC diesel containing high aromatics，30%～50% of good quality catalytic reforming feed with more than 50% of C6～C9 aromatics and 32% BTX could be produced，and the upgraded diesel quality was improved largely compared with that of the feed.
