(EN) A process for the sulfiding of a hydrodesulfurization catalyst in a distillation column recator comprising the steps of:(a) drying the catalyst with an inert gas;(b) filling th e 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 distillation column reactor to a temperature above the decomposition temperature of the sulffiding agent;(f) introducing a sulfiding agent;(h) observingd asid sulfiding agent breadthrough in the overhead;(i) increasing temperature to a second temperature;(i) holding said second temperature for a period of time.
