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.

摘要:
A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant and animal fats and oils. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel. Water is added to the deoxygenation reaction to drive carbon monoxide and water to react to form hydrogen and carbon dioxide. The hydrogen is then consumed by the reactions. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties.
