Process and equipment for fluid catalytic cracking for the production of middle distillates of low aromaticity

摘要

The present invention relates to a process and equipment for fluid catalytic cracking for the production of middle distillates of low aromaticity that comprises cracking a mixed feed consisting of heavy fractions of hydrocarbons, in the absence of added hydrogen, employing a catalyst of low activity and low acidity and contacting the feed for at least 30 seconds, in a dense-bed FCC reactor to produce an effluent constituted of fractions of middle distillates and naphtha of low aromaticity.
