Claim 14:
15. A process for hydroprocessing a hydrocarbon feedstock, the process comprising contacting the hydrocarbon feedstock with hydrogen in the presence of a bulk catalyst at hydroprocessing conditions to give at least one product, wherein the bulk catalyst is prepared by sulfiding a bulk catalyst precursor having a formula of:

Av[Ni(OH)x(L)py]z[MomW1-mO4][Ti(OH)nO2-n/2]w 

wherein:
(i) A is an alkali metal cation, a rare earth metal cation, an ammonium cation, an organic ammonium cation, phosphonium cation, or a combination thereof;
(ii) L is an organic compound-based component; and
(iii) 0≤y≤−2/p; 0≤x<2; 0≤v<2; 0<z; 0<m<1; 0<n<4; 0.1<w/(z+1)<10;

wherein the bulk catalyst precursor is defined by a region of a quaternary phase diagram defined by eight points ABCDEFGH and wherein the eight points, on a metal oxide basis (wt. %), are: A (Ni=52.5, Mo=3.5, W=14, Ti=30), B (Ni=38.5, Mo=17.5, W=14, Ti=30), C (Ni=21, Mo=17.5, W=31.5, Ti=30), D (Ni=35, Mo=3.5, W=31.5, Ti=30), E (Ni=60, Mo=4, W=16, Ti=20), F (Ni=44, Mo=20, W=16, Ti=20), G (Ni=24, Mo=20, W=36, Ti=20), and H (Ni=40, Mo=4, W=36, Ti=20).
