A process for starting up a hydrotreating process using a bulk metal catalyst. The process comprises the steps of providing a hydrocarbon feed stream containing less than 100 ppmw nitrogen containing species; and adding a nitrogen-containing compound to the hydrocarbon feed stream followed by contacting the resulting feed stream with the bulk metal catalyst in the presence of hydrogen and a sulfur-containing species.

1. A process for starting up a hydrotreating process using a bulk metal catalyst, said process comprising the steps of: i) providing a hydrocarbon feed stream containing less than 100 ppmw nitrogen-containing species;ii) adding a nitrogen-containing compound to said hydrocarbon feed stream to provide a resultant feed stream containing more than 100 ppmw nitrogen-containing species (based on the overall weight of the feed stream); andiii) contacting the resultant feed stream with the bulk metal catalyst in the presence of hydrogen and a sulfur-containing species; wherein the nitrogen-containing compound is selected from the group consisting of polyfunctional amines, pyridines and their derivatives, quaternary ammonium compounds, decylamine, pyrroles, indoles, carbazoles, imidazoles, pyrrazoles, oxazoles, S,N heteroaromatics, amides, nitriles and EDTA, NTA, EGTA and DPTA; and wherein the bulk metal catalyst is a composition of the general formula (I): (X)b(M)c(Z)d(Y)e wherein X is at least one Group VIII metal selected from the group consisting of nickel, cobalt and iron, M is a group VIb metal selected from the group consisting of chromium, molybdenum and tungsten, Y is oxygen, and Z is selected from the group of elements consisting of aluminum, silicon, magnesium, titanium, zirconium, boron and zinc, wherein Z together with the oxygen component as the element for Y forms a refractory inorganic oxide, and wherein b, c, d and e represent relative molar ratio values. 2. A process according to claim 1, wherein the hydrocarbon feed stream containing less than 100 ppmw nitrogen-containing species is a feed stream which has already been treated in a process which reduces the amount of nitrogen contained therein. 3. A process according to claim 1, wherein c is the integer 1, the ratio d:c is in the range of from 0:1 to 20:1, and the ratio e:c is in the range of from 1:1 to 50:1. 4. A process according to claim 1, wherein the nitrogen-containing compound is selected from the group consisting of polyfunctional amines, pyridines and their derivatives, and quaternary ammonium compounds. 5. A process according to claim 1, wherein the nitrogen-containing compound is decylamine. 6. A process according to claim 5, wherein the resultant feed stream is contacted with the bulk metal catalyst in the presence of hydrogen and a sulfur-containing species at a hydrogen partial pressure in the range of from 2 to 10 Mpa. 7. A process according to claim 6, wherein while the resultant feed stream is contacted with the bulk metal catalyst in the presence of hydrogen and a sulfur-containing species the temperature is increased during one or more phases and during each phase the temperature is increased at a rate in the range of from 1 to 50° C./hour. 8. A process for hydrotreating a hydrocarbon feedstock, said process comprising the steps of: i) providing a hydrocarbon feed stream containing less than 100 ppmw nitrogen-containing species;ii) adding a nitrogen-containing compound to said hydrocarbon feed stream to provide a resultant feed stream containing more than 100 ppmw nitrogen-containing species (based on the overall weight of the feed stream);iii) contacting the resultant feed stream with a bulk metal catalyst in the presence of hydrogen and a sulfur-containing species; wherein the nitrogen-containing compound is selected from the group consisting of polyfunctional amines, pyridines and their derivatives, quaternary ammonium compounds, decylamine, pyrroles, indoles, carbazoles, imidazoles, pyrrazoles, oxazoles, S,N heteroaromatics, amides, nitriles and N-containing complexing agents; andiv) subsequently contacting the resultant bulk metal catalyst with the hydrocarbon feedstock in the presence of hydrogen. 9. A process according to claim 8, wherein the bulk metal catalyst is a composition of the general formula (I): (X)b(M)c(Z)d(Y)e wherein X is at least one Group VIII metal selected from the group consisting of nickel, cobalt and iron, M is a group VIb metal selected from the group consisting of chromium, molybdenum and tungsten, Y is oxygen, and Z is selected from the group of elements consisting of aluminum, silicon, magnesium, titanium, zirconium, boron and zinc, wherein Z together with the oxygen component as the element for Y forms a refractory inorganic oxide and b, c, d and e represent relative molar ratio values. 10. A process according to claim 9, wherein c is the integer 1, the ratio d:c is in the range of from 0:1 to 20:1, and the ratio e:c is in the range of from 1:1 to 50:1. 11. A process according to claim 8, wherein the resultant feed stream is contacted with the bulk metal catalyst in the presence of hydrogen and a sulfur-containing species at a hydrogen partial pressure in the range of from 2 to 10 Mpa. 12. A process according to claim 8, wherein while the resultant feed stream is contacted with the bulk metal catalyst in the presence of hydrogen and a sulfur-containing species the temperature is increased during one or more phases and during each phase the temperature is increased at a rate in the range of from 1 to 50° C./hour. 13. A process according to claim 1, wherein the nitrogen-containing compound is a polyfunctional amine. 14. A process according to claim 1, wherein the nitrogen-containing compound is selected from the group consisting of pyrroles, indoles, carbazoles, imidazoles, pyrazoles, oxazoles, and S,N heteroaromatics. 15. A process according to claim 8, wherein the nitrogen-containing compound is an N-containing complexing agent selected from the group consisting of EDTA, NTA, EGTA and DPTA. 16. A process for starting up a hydrodesulfurization (HDS) process which utilizes a bulk metal catalyst comprising nickel and molybdenum, said process comprising the steps of: i) providing a hydrocarbon feed stream containing less than 100 ppmw organic nitrogen-containing species;ii) adding a C4 to C20 amine to said hydrocarbon feed stream to provide a resultant feed stream containing more than 100 ppmw organic nitrogen-containing species (based on the overall weight of the feed stream); andiii) contacting the resultant C4 to C20 amine-containing hydrocarbon feed stream with said bulk metal catalyst in the presence of hydrogen and a sulfur-containing species, whereby said amine prevents the formation of an additional nickel sub-sulfide Ni7S6 phase thereby improving the HDS activity of said bulk metal catalyst.
