Abstract:
A catalyst that is useful for the removal of arsenic from hydrocarbon feedstocks. The catalyst comprises an alumina support, underbedded molybdenum and phosphorus components, and an overlayer of a nickel component. The catalyst further has the unique property of having a surface nickel-to-molybdenum atomic ratio of greater than 1.8 with a bulk nickel-to-molybdenum atomic ratio of less than 2.2. The nickel accessibility factor of the catalyst is greater than 1.2. The catalyst is prepared by the application of two metals impregnation steps with associated calcination steps that in combination provide for the underbedded metals and overlayer of nickel.
