Technology for producing light aromatics from heavy aromatics

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" Co aromatics and 32% BTX could be produced, and the
upgraded diesel quality was improved largely compared with that of the feed.
Key words: FCC diesel; hydrocracking; heavy aromatics; light aromatics
