ABSTRACT:
A process for removing arsenic from a mineral oil feedstock containing at least 2 ppmw arsenic comprises contacting said feedstock at elevated temperatures with a catalytic absorbent comprising a nickel sulfide and a molybdenum sulfide composited with a refractory oxide, said nickel sulfide and said refractory oxide each being present in relatively large proportions. Under preferred conditions a product oil stream containing less than 2 ppmw arsenic is continuously obtained from said contacting until a weight of arsenic at least equivalent to that of the nickel in the catalytic absorbent has been absorbed thereon.
