摘要： A cost effective method for reutilizing exiting refinery equipment associated with either a Reformer Unit or Isomerization Unit by converting such units into units and associated processes for hydrodesulfurizing and cracking naphtha feedstocks into light plant gases and chemical feedstocks. These existing Reformer or Isomerization units and processes can be converted into the processes described herein with very little capital expenditures, essentially utilizing almost all of the existing unit equipment, and with little to no major equipment replacements. The processes disclosed herein also effectively reduce the overproduction of naphtha currently experienced in many modern refineries that have resulted from a reduction in overall demand of gasoline products relative to other refinery products.
摘要翻译： 通过将这些单元转化为单元和加氢脱硫和裂解石脑油原料的轻质植物气体和化学原料的相关工艺，再利用与重整单元或异构化单元相关的现有炼油设备的成本有效的方法。 这些现有的改革者或异构化单位和过程可以用很少的资本支出转换为本文描述的过程，基本上利用了几乎所有的现有单位设备，几乎没有重大的设备替代品。 本文公开的方法还有效地减少了许多现代炼油厂目前经验的石脑油过度生产，这是由于汽油产品相对于其他炼油产品的总体需求减少而导致的。

摘要： Selective and deep desulfurization of a high sulfur content mogas naphtha, with reduced product mercaptans and olefin loss, is achieved by a two stage, vapor phase hydrodesulfurization process with interstage separation of at least 80 vol. % of the H2S formed in the first stage from the first stage, partially desulfurized naphtha vapor effluent fed into the second stage. At least 70 wt. % of the sulfur is removed in the first stage and at least 80 wt. % of the remaining sulfur is removed in the second stage, to achieve a total at least 95 wt. % feed desulfurization, with no more than a 60 vol. % feed olefin loss. 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.

摘要： A reaction inhibitor can be used to reduce catalyst activity at the beginning of a naphtha selective hydrodesulfurization process. The use of the reaction inhibitor can allow greater flexibility in selecting the reaction conditions to accommodate both the start and end of the hydrodesulfurization process. The reaction inhibitor can be removed during the hydrodesulfurization process, possibly in conjunction with modification of the reaction temperature, in order to maintain a substantially constant amount of sulfur in the naphtha product.

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： The invention relates to naphtha hydrodesulfurization incorporating either high temperature depressurization or controlled heating for mercaptan removal. More particularly, the invention relates to a naphtha hydrodesulfurization process, wherein the hot naphtha exiting the desulfurization reactor contains mercaptans, most of which are removed without olefin loss, by depressurizing the hot naphtha, thermally treating the hot naphtha, or some combination thereof. The desulfurized naphtha may be cooled and condensed to a liquid, separated from the gaseous H2S, stripped and sent to a mogas pool.
