Multi-stage hydrodesulfurization of cracked naphtha streams with a stacked bed reactor
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.

用于选择性加氢脱硫含有大量烯烃和有机结合硫的石脑油流的方法。 通过使该石脑油流过含有第一加氢脱硫催化剂床的第一反应区，然后将所得产物流通过含有第二加氢脱硫催化剂床的第二反应区，该第二反应区含有较低的 催化金属的含量高于第一加氢脱硫催化剂。
