20110056870 | INTEGRATED FLUID CATALYTIC CRACKING PROCESS FOR OBTAINING HYDROCARBON BLENDS HAVING A HIGH QUALITY AS FUEL - The present invention relates to an integrated fluid catalytic cracking process (FCC) which allows hydrocarbon blends to be obtained having a high quality as fuel. In particular, it relates to an integrated process comprising a fluid catalytic cracking step wherein hydrocarbon cuts of an oil origin are converted into blends with a high content of light cycle oil (LCO) having a high quality in terms of density and nature of the aromatic products contained, which, after a separation and a hydrotreating step, is subjected to upgrading by treatment with hydrogen and a catalyst comprising one or more metals selected from Pt, Pd, Ir, Ru, Rh and Re and a silicoaluminate of an acidic nature. | 03-10-2011 |
