摘要: The possible origins of sulfur impurities in FCC gasoline are reviewed and discussed. Their mechanism formation during the process as well their transformation on hydrotreating catalysts also examined. article focuses desulfurization by means catalytic processes considering fact that deep must be achieved (in accordance with new regulations) while preserving octane rating fraction. various parameters (presence a promoter, nature modification support, additives poisons) which may influence selectivity hydrodesulfurization (HDS) versus olefin hydrogenation Existing potential for HDS preservation described.
