    摘要: A desulfurization system is operated in a manner which optimizes sulfur removal and octane retention. When the desulfurization reactor is operated at a specific ratio of total pressure to hydrogen partial pressure (PT/PH) and/or within a specific temperature range, optimum sulfur removal and octane retention are realized. The desulfurization reactor can be maintained at these optimized operating conditions by automatically adjusting one or more operating parameters of the desulfurization reactor in order to maintain a substantially constant hydrogen partial pressure (PH) in the reactor. Maintaining a relatively constant hydrogen partial pressure (PH) in the desulfurization reactor helps ensure a relatively consistent degree of desulfurization.

    摘要: A process where the need to circulate hydrogen through the catalyst is eliminated is provided. This is accomplished by mixing and/or flashing the hydrogen and the oil to be treated in the presence of a solvent or diluent in which the hydrogen solubility is “high” relative to the feed. The type and amount of diluent added, as well as the reactor conditions, can be set so that all of the hydrogen required in the hydroprocessing reactions may be available in solution. The oil/diluent/hydrogen solution can then be fed to a plug flow reactor packed with catalyst where the oil and hydrogen react. No additional hydrogen is required, therefore, hydrogen recirculation is avoided and trickle bed operation of the reactors is avoided. Therefore, the large trickle bed reactors can be replaced by much smaller tubular reactor.
