Metals contained in a hydrocarbon containing feed stream are at least partially removed by contacting the hydrocarbon containing feed stream under suitable demetallization conditions with hydrogen and a catalyst composition comprising an alumina-containing support and nickel arsenide, NiAs x . The life and activity of the catalyst composition can be increased by introducing a decomposable compound of a metal selected from the group consisting of the metals of Group IV-B, Group V-B, Group VI-B, Group VII-B and Group VIII of the Periodic Table into the hydrocarbon containing feed stream during or prior to contacting the feed stream with hydrogen and the catalyst composition. The preferred nickel arsenide catalyst composition is prepared by reduction of alumina-supported nickel arsenate with hydrogen gas.

A process in accordance with claim 1 wherein said catalyst composition is alumina-supported NiAs x, wherein x ranges from about 0.6 to about 1.0. 3. A process in accordance with claim 1 wherein said catalyst composition is prepared by reduction of alumina-supported nickel arsenate with hydrogen gas. 4. A process in accordance with claim 3 comprising utilizing a catalyst wherein the nickel content ranges from about 1 to about 30 weight percent based on the weight of the finished catalyst composition, and the arsenic content ranges from about 0.5 to 50 weight percent based on the weight of the finished catalyst composition. 5. A process in accordance with claim 3 wherein the alumina-supported arsenate, before reduction with H 2, has a surface area (determined by BET/N 2 ) ranging from about 20 to about 300 m 2 /g and a pore volume (determined by water absorption) of about 0.5 to about 1.5 cc/g. 6. A process in accordance with claim 5 wherein the nickel content ranges from about 10 to about 20 weight percent based on the weight of the finished catalyst composition, and the arsenic content ranges from about 10 to about 20 weight percent based on the weight of the finished catalyst composition. 7. A process in accordance with claim 1 wherein said suitable demetallization conditions comprise a reaction time between said catalyst composition and said hydrocarbon containing feed stream in the range of about 0.05 hours to about 10 hours, a temperature in the range of about 250° C. to about 550° C., a pressure in the range of up to about 5000 psig and a hydrogen flow rate in the range of about 100 to about 10,000 standard cubic feet per barrel of said hydrocarbon containing feed stream. 8. A process in accordance with claim 7 wherein said suitable demetallization conditions comprise a reaction time between said catalyst composition and said hydrocarbon containing feed stream in the range of about 0.4 hours to about 4 hours, a temperature in the range of 350° C. to about 450° C., a pressure in the range of about 100 to about 2500 psig and a hydrogen flow rate in the range of about 1000 to about 6000 standard cubic feet per barrel of said hydrocarbon containing feed stream. 9. A process in accordance with claim 7 wherein the hydrocarbon containing feed stream is selected from the group consisting of crude oils, petroleum products, coal pyrolyzates, coal extraction products, coal liquefaction products, products from tar sands, shale oil and products from shale oil. 10.

A process in accordance with claim 1 wherein at least one decomposable metal compound is introduced into said hydrocarbon containing feed stream prior to the contacting of said hydrocarbon containing feed stream with said catalyst composition, wherein the metal, chemically bound in said decomposable metal compound, is selected from the group consisting of the metals of Group IV-B, Group V-B, Group VI-B, Group VII-B and Group VIII of the Periodic Table. 12. A process in accordance with claim 11 wherein said decomposable metal compound is a carbonyl, acetate, acetylacetonate, octoate, naphthenate, dithiocarbamate, or dithiophosphate of said metal or metals. 13. A process in accordance with claim 12 wherein the metal in said decomposable metal compound is molybdenum. 14. A process in accordance with claim 13 wherein said decomposable metal compound is molybdenum hexacarbonyl. 15. A process in accordance with claim 11 wherein a sufficient quantity of said decomposable metal compound is added to said hydrocarbon containing feed stream to result in a concentration of the metal, chemically bound in said decomposable metal compound, ranging from about 1 to about 1000 ppm metal in said hydrocarbon containing feed stream. 16. A process in accordance with claim 15 wherein a sufficient quantity of said decomposable metal compound is added to said hydrocarbon containing feed stream to result in a concentration of the metal, chemically bound in said decomposable metal compound, ranging about 5 to about 100 ppm metal in said hydrocarbon containing feed stream. 17. A process in accordance with claim 1 wherein said catalyst composition is first impregnated with at least one decomposable compound of a metal selected from the group consisting of metals of Group IVB, VB, VIB, VIIB and VIII of the Periodic Table, and the hydrocarbon containing feed stream is then contacted under suitable demetallizing conditions with hydrogen and the thus impregnated catalyst composition so as to produce a hydrocarbon containing steam having reduced content of metals selected from the group consisting of vanadium and nickel. 18. A process in accordance with claim 17 wherein said decomposable compound is selected from the Group consisting of carbonyl, acetate, actylacetonate, octoate, naphthenate, dithiocarbamate and dithiophosphate. 19.
