Abstract: PROBLEM TO BE SOLVED: To provide a hydrodesulfurization process that, in one aspect, selectively desulfurizes a hydrocarbon stream with minimal olefin saturation and minimal recombination of sulfur into mercaptans.
SOLUTION: The hydrodesulfurization process includes a multi-stage reaction zone including at least first and second serial hydrodesulfurization reaction zones that sequentially remove sulfur from the hydrocarbon stream. The hydrodesulfurization process is particularly suited to selectively desulfurize an olefinic naphtha hydrocarbon stream such as FCC naphtha, steam cracked naphtha, coker naphtha or other gasoline boiling hydrocarbon streams.

Abstract: A process (10) is provided for improving the cold flow properties of a hydrocarbon stream (14) employing a substantially liquid-phase continuous hydroisomerization zone (12) where the reaction zone has a substantially constant level of dissolved hydrogen throughout without the addition of additional hydrogen external to the reaction zone.

Abstract: En un aspecto, se proporciona un proceso de hidrodesulfurización que desulfuriza selectivamente una corriente de hidrocarburos con una mínima saturación de olefinas y una mínima recombinación de azufre en mercaptano. En otro aspecto, el proceso incluye una zona multietápica de reacción que incluye cuando menos zonas de reacción primera y segunda en serie de hidrodesulfurización que eliminan secuencialmente azufre de una corriente de hidrocarburos. En otro aspecto más, el proceso es particularmente apropiado para desulfurizar selectivamente una corriente de hidrocarburos de nafta olefínica, como nafta FCC, nafta desintegrada al vapor, nafta coquificada u otras corrientes de hidrocarburos con punto de ebullición de gasolinas.

Abstract: Methods (10, 110, 210) of hydrocracking hydrocarbon streams (12, 112, 212) are provided that employ substantially liquid-phase continuous hydroprocessing conditions. In one aspect, the method includes a separate hydrotreating and hydrocracking system where the hydrocracking zone (24) is a substantially liquid-phase continuous system. In another aspect, the method includes a two stage hydrocracking system where one or both of the hydrocracking zones (113, 124) (213, 224) are a substantially liquid-phase continuous reaction system.
