| titleOfInvention | Multi-step hydrodesulphurisation process |
| abstract | PCT No. PCT/GB90/00718 Sec. 371 Date Dec. 11, 1991 Sec. 102(e) Date Dec. 11, 1991 PCT Filed May 9, 1990 PCT Pub. No. WO90/13617 PCT Pub. Date Nov. 15, 1990.Liquid sulphur-containing hydrocarbon feedstock is passed through two or more hydrodesulfurization zones and connected in a series each containing a packed bed of solid sulfurized catalyst. The liquid is passed from the first zone to the next until the final zone. Make up hydrogen is supplied to a hydrodesulfurization zone (i) other than the first hydrodesulfurization zone; hydrogen-containing gas is recovered from each hydrodesulfurization zone. The first hydrodesulfurization zone is supplied with hydrogen-containing gas recovered from a subsequent hydrodesulfurization zone. Hydrogen-containing gas recovered from the first hydrodesulfurization zone is purged. Liquid material recovered from the first hydrodesulfurization zone is recycled to the inlet of the hydrosulfurization zone so as to provide diluent for admixture with liquid feedstock. Any other hydrodesulfurization zone other than the first hydrodesulfurization zone and other than the hydrodesulfurization zone of step (i) is supplied with hydrogen-containing gas recovered from another hydrodesulfurization zone. The sulfur content of the hydrogen-containing gas and of the liquid hydrocarbon feedstock supplied to the first hydrodesulfurization zone is monitored and, if necessary, sulfur-containing material selected from hydrogen sulfide and active sulfur-containing materials is supplied to the first hydrodesulfurization zone so as to maintain the catalyst charge thereof in sulfided form. |
