1. A process comprising:contacting under arsenic removal process conditions a hydrocarbon feed, containing arsenic, with a catalyst comprising: alumina; at least 8 weight percent nickel; at least 8 weight percent molybdenum; and between about 0.1 weight percent to about 3 weight percent phosphorous;
1. A process comprising:contacting under arsenic removal process conditions a hydrocarbon feed, containing arsenic, with a catalyst comprising: alumina; at least 8 weight percent nickel; at least 8 weight percent molybdenum; and between about 0.1 weight percent to about 3 weight percent phosphorous; wherein said catalyst is prepared by forming a support, said support comprises alumina and nickel, wherein said nickel is present in said support in an amount of no more than 1 weight percent, and wherein said support is formed by mixing alumina, water, a nickel compound, and an acid selected from the group consisting of nitric acid and acetic acid, to thereby form a mixture thereof, extruding said mixture, and calcining, at a first calcining temperature, said mixture to thereby form said support; impregnating said support with a first solution of a nickel compound to thereby form an impregnated support; and calcining, at a second calcining temperature, said impregnated support to thereby provide a calcined impregnated support; incorporating molybdenum and phosphorous into said calcined impregnated support to thereby provide a molybdenum/phosphorous incorporated material; and thereafter, calcining, at a third calcining temperature, said molybdenum/phosphorous incorporated material to thereby provide said catalyst. 2. A process as recited in claim 1, wherein the amount of nickel in said catalyst is at least 10 weight percent.3. A process as recited in claim 2, wherein the amount of molybdenum in said catalyst is in the range of from 8 weight percent to 14 weight percent.4. A process as recited in claim 3, wherein said first calcining temperature is in the range of from 450° C. to 700° C., wherein said second calcining temperature is in the range of at least 427° C., and said third calcining temperature is in the range of from 450° C. to 700° C.5. A process as recited in claim 4, wherein said incorporating step includes impregnating said calcined impregnated support with a second solution containing a molybdenum compound and phosphoric acid to thereby provide said molybdenum/phosphorous incorporated material so as to provide said catalyst.6. A process as recited in claim 5, wherein said nickel compound is nickel nitrate.7. A process as recited in claim 6, wherein said arsenic removal process conditions include a pressure between about 2860 kPa and about 18,720 kPa, a temperature between about 260° C. and about 490° C., a hydrogen treat gas rate between 180 m3/m3 and 1600 m3/m3, and a liquid hourly space velocity between about 0.1 hr?1 and about 40 hr?1.8. A process comprising:contacting under arsenic removal process conditions a hydrocarbon feed, containing arsenic, with a catalyst, consisting essentially of: alumina; at least 8 weight percent nickel; at least 8 weight percent molybdenum; and between about 0.1 weight percent to about 3 weight percent phosphorous; wherein said catalyst is prepared by forming a support, said support comprises alumina and nickel, wherein said nickel is present in said support in an amount of no more than 1 weight percent, and wherein said support is formed by mixing alumina, water, a nickel compound, and an acid selected from the group consisting of nitric acid and acetic acid, to thereby form a mixture thereof, extruding said mixture, and calcining, at a first calcining temperature, said mixture to thereby form said support; impregnating said support with a first solution of a nickel compound to thereby form an impregnated support; and calcining, at a second calcining temperature, said impregnated support to thereby provide a calcined impregnated support; incorporating molybdenum and phosphorous into said calcined impregnated support to thereby provide a molybdenum/phosphorous incorporated material; and thereafter, calcining, at a third calcining temperature, said molybdenum/phosphorous incorporated material to thereby provide said catalyst. 9. A process as recited in claim 8, wherein the amount of nickel in said catalyst is at least 10 weight percent.10. A process as recited in claim 9, wherein the amount of molybdenum in said catalyst is in the range of from 8 weight percent to 14 weight percent.11. A process as recited in claim 10, wherein said first calcining temperature is in the range of from 450° C. to 700° C., wherein said second calcining temperature is in the range of at least 427° C., and said third calcining temperature is in the range of from 450° C. to 700° C.12. A process as recited in claim 11, wherein said incorporating step includes impregnating said calcined impregnated support with a second solution containing a molybdenum compound and phosphoric acid to thereby provide said molybdenum/phosphorous incorporated material so as to provide said catalyst.13. A process as recited in claim 12, wherein said nickel compound is nickel nitrate.14. A process as recited in claim 13, whereina process as recited in claim 6, wherein said arsenic removal process conditions include a pressure between about 2860 kPa and about 18,720 kPa, a temperature between about 260° C. and about 490° C., a hydrogen treat gas rate between 180 m3/m3 and 1600 m3/m3, and a liquid hourly space velocity between about 0.1 hr?1 and about 40 hr?1.
