INTEGRATED FLUID BED CATALYTIC CRACKING PROCESS FOR OBTAINING HIGH-QUALITY HYDROCARBON MIXTURES AS FUEL

摘要

The present invention relates to an integrated fluid bed catalytic cracking process (FCC) which allows the production of high-quality hydrocarbon mixtures as fuel. In particular the invention relates to an integrated process comprising a fluid bed catalytic cracking stage in which hydrocarbon cuts of a petroliferous origin are converted, in the presence of a catalyst, with at least two components containing ERS-10 zeolite, into mixtures with a high content of light cycle oil (LCO) having a high quality in terms of density and nature of the aromatic compounds contained therein. After a separation stage and a hydrotreatment stage, the LCO cut is subjected to an upgrading stage by treatment with hydrogen and with a catalyst comprising one or more metals selected from Pt, Pd, Ir, Ru, Rh and Re and a silico-aluminate of an acid nature.
