Tungsten-containing bulk catalysts, method of making the same, and their use in low pressure diesel hydroprocessing

A method of making a bulk catalyst composition comprising:

• (i) combining tungstic acid, cobalt carbonate, and optionally molybdenum trioxide, and
• (ii) reacting the tungstic acid, cobalt carbonate, and optional molybdenum trioxide to form a catalyst composition,
• wherein the cobalt carbonate has a first X-ray powder diffraction pattern comprising characteristic diffraction peaks having d-spacing values of about 10.03 Å, 5.91 Å, 4.35 Å, and 4.21 Å,
• wherein the catalyst composition comprises a compound having a formula
• CoyW1-xMxO4 (I),
• wherein
• M is Mo;
• 0.5≥x≥0;
• and
• 1≤y≤4,
• wherein the compound is substantially in a hexagonal phase and has a second X-ray powder diffraction pattern comprising characteristic diffraction peaks having d-spacing values of about 2.90 Å, 2.56 Å, and 1.73 Å, and
• wherein the second X-ray powder diffraction pattern is free of diffraction peaks below a two-theta value of 18°.
