Abstract:
A process for the sulfiding of a hydrodesulfurization catalyst in a distillation column reactor comprising the steps of:(a) drying the catalyst with an inert gas; (b) filling the distillation column reactor with a sulfiding solvent containing sulfur; (c) establishing hydrocarbon feed and hydrogen flow rates; (d) begin recycling of sulfiding solvent; (e) heating the distillation column reactor to a temperature above the decomposition temperature of the sulfiding agent; (f) introducing a sulfiding agent; (g) observing the water by-product azeotrope overhead and collecting the water; (h) observing said sulfiding agent breakthrough in the overhead; (i) increasing temperature to a second temperature; and (j) holding said second temperature for a period of time.
