Abstract:
1. A method of desulfurizing a hydrocarbon-containing fluid, said method comprising the steps of: (a) contacting said hydrocarbon-containing fluid with solid particles in a desulfurization zone under desulfurization conditions sufficient to remove sulfur from said hydrocarbon-containing fluid, thereby providing sulfur loaded solid particles; (b) batchwise transporting said sulfur loaded solid particles from said desulfurization zone to a lock hopper; (c) depressurizing said lock hopper to a drain pressure, thereby providing a depressurized filled lock hopper; (d) batchwise transporting said sulfur loaded solid particles from said depressurized filled lock hopper to a regenerator feed drum; (e) substantially continuously transporting said sulfur loaded solid particles from said regenerator feed drum to a regeneration zone; (f) contacting said sulfur loaded solid particles with an oxygen-containing regeneration stream in said regeneration zone under regeneration conditions sufficient to remove sulfur from said sulfur loaded solid particles, thereby providing regenerated solid particles; (g) batchwise transporting said regenerated solid particles from said regeneration zone to said lock hopper that previously contained said sulfur loaded particles from said desulfurization zone; (h) pressurizing said lock hopper to a fill pressure, thereby providing a pressurized lock hopper; (i) batchwise transporting said regenerated solid particles from said pressurized lock hopper to a reducing zone; and (j) contacting said regenerated solid particles with a hydrogen-containing reducing stream in said reducing zone under reducing conditions sufficient to reduce said solid particles, thereby providing reduced solid particles.
