摘要： A process for the selective hydrodesulfurization of naphtha streams containing a substantial amount of olefins and organically bound sulfur. The naphtha stream is selectively hydrodesulfurized by passing it through a first reaction zone containing a bed of a first hydrodesulfurization catalyst, then passing the resulting product stream through a second reaction zone containing a bed of a second hydrodesulfurization catalyst, which second hydrodesulfurization catalyst contains a lower level of catalytic metals than the first hydrodesulfurization catalyst.

摘要： Naphtha desulfurization with reduced product mercaptans is achieved by reacting a naphtha feed containing sulfur compounds and olefins with hydrogen in the presence of a hydrosesulfurization catalyst at reaction conditions including a temperature of from 290-425° C., a pressure of from 60-150 psig, and a hydrogen gas ratio of from 2000-4000 scf/b. It has been found that desulfurizing within these narrow conditions permits deep desulfurization with reduced mercaptan reversion, to produce a naphtha product with low total sulfur and low mercaptan sulfur levels.

摘要： Naphtha hydrodesulfurization selectivity is increased by reducing the amount of COX (CO plus ½ CO2) in the hydrodesulfurization reaction zone to less than 100 vppm. While this is useful for non-selective hydrodesulfurization, it is particularly useful for selectively desulfurizing an olefin-containing naphtha without octane loss due to olefin saturation by hydrogenation. The COX reduction is achieved by removing COX from the treat gas before it is passed into the reaction zone.
摘要翻译： 通过将加氢脱硫反应区中的CO 2 CO 2（CO + 1/2 CO 2）的量减少到小于100vppm来增加石脑油加氢脱硫选择性。 虽然这对于非选择性加氢脱硫是有用的，但是通过氢化由于烯烃饱和而没有辛烷值损失选择性脱硫含烯烃的石脑油特别有用。 在处理气体进入反应区之前，通过从处理气体中除去CO x X而实现CO 2还原。

摘要： A process for the selective hydrodesulfurization of olefinic naphtha streams containing a substantial amount of organically bound sulfur and olefins. The olefinic naphtha stream is selectively hydrodesulfurized in a first sulfur removal stage and resulting product stream, which contains hydrogen sulfide and organosulfur is fractionated at a temperature to produce a light fraction containing less than about 100 wppm organically bound sulfur and a heavy fraction containing greater than about 100 wppm organically bound sulfur. The light fraction is stripped of at least a portion ofits hydrogen sulfide and can be collected or passed to gasoline blending. The heavy fraction is passed to a second sulfur removal stage wherein at least a portion of any remaining organically bound sulfur is removed.

The second stage temperature and space velocity are preferably greater than in the first. The hydrodesulfurization catalyst preferably contains a low metal loading of Co and Mo metal catalytic components on an alumina support.
