Abstract:
A process for the hydrodesulfurization of naphtha in a distillation column reactor having a stripping section and a rectification section, comprising the steps of:(a) feeding a naphtha boiling range hydrocarbon stream containing organic sulfur compounds and hydrogen to a distillation column reactor above said stripping section;(b) concurrently in said distillation column reactor(i) separating said naphtha into a light boiling range naphtha and a heavy boiling range naphtha(ii) contacting the heavy boiling range naphtha and hydrogen with a hydrodesulfurization catalyst in said stripping section to selectively react the heavier organic sulfur compounds with said hydrogen to form H.sub.2 S;(c) removing said light boiling range naphtha, H.sub.2 S and unreacted hydrogen from said distillation column reactor as overheads;(d) removing said heavier boiling range naphtha from said distillation column reactor as bottoms.
