Abstract: 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.

Abstract translation: 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。
