Countercurrent desulfurization process for refractory organosulfur heterocycles |
摘要 |
A process for the hydrodesulfurization (HDS) of the multiple condensed ring heterocyclic organosulfur compounds present in petroleum and chemical streams. The stream is passed through at least one reaction zone countercurrent to the flow of a hydrogen-containing treat gas, and through at least one sorbent zone. The reaction zone contains a bed of Group VIII metal-containing hydrodesulfurization catalyst and the sorbent zone contains a bed of hydrogen sulfide sorbent material. |
