1. 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 wherein the region is defined by ten points ABCDEFGHIJ and wherein the ten points, on a metal oxide basis (wt. %), are: A (Ni=39, Mo=1, W=41, Ti=20), B (Ni=39, Mo=1, W=72, Ti=20), C (Ni=9, Mo=17, W=54, Ti=20), D (Ni=31, Mo=25, W=24, Ti=20), E (Ni=40, Mo=14, W=26, Ti=20), F (Ni=34, Mo=1, W=36, Ti=30), G (Ni=7, Mo=1, W=63, Ti=30), H (Ni=8, Mo=15, W=48, Ti=30), I (Ni=27, Mo=22, W=21, Ti=30), and J (Ni=35, Mo=12, W=23, Ti=30).
