ABSTRACT:
A process for removal of arsenic from a hydrocarbon stream containing arsenic together with mercaptan and non-mercaptan sulfur compounds. The hydrocarbon stream is passed through at least two mercaptan oxidizing reactors in series wherein the mercaptans are oxidized to disulfides to produce a low mercaptan liquid containing no more than 1.5 ppm sulfur as mercaptans. The low mercaptan liquid is passed over an arsenic sorbent catalyst containing less than 20 weight percent gamma alumina to selectively sorb arsenic substantially without sorbing non-mercaptan sulfur compounds.
