Carlson, D H.J.

A catalytic process for treating sour petroleum distillates is disclosed. A sour petroleum distillate containing phenolic catalyst toxins to toxin precursors are pretreated in contact with an oxidizing agent and a charcoal adsorbent at conditions to oxidize a portion of the mercaptan content of the distillate to disulfides, and to adsorb substantially all of the phenolic toxin and toxin precursors from the distillate. The distillate is thereafter treated in an alkaline environment in contact with an oxidizing agent and a supported metal phthalocyanine catalyst to oxidize the residual maercaptans contained therein to disulfides.
