Claims
- 1. In a catalyst for the continuous-flow hydrogenation and denitrogenation of carbonaceous liquids produced in the solvent refining of coal containing combined sulfur of 0.2-0.8% and combined nitrogen of 0.5-1.5% by weight within carbonaceous compounds, said catalyst having a base comprising a major proportion of alumina with deposited oxides of catalytic metals, the improved combination comprising a base material that includes a surface area of about 250 m.sup.2 /g, a pore volume of about 0.7 ml/g and an average pore diameter of 120-130 Angstroms and said deposited oxides of catalytic metal include in percent total weight 10-11% WO.sub.3, 2-3% NiO, 6-7% CoO and 12-13% MoO.sub.3.
- 2. In a catalyst for the continuous-flow hydrogenation and denitrogenation of carbonaceous liquids produced in the solvent refining of coal containing combined sulfur of 0.2-0.8% and combined nitrogen of 0.5-1.5% by weight within carbonaceous compounds, said catalyst having a base comprising a major proportion of alumina with deposited oxides of catalytic metals, the improved combination comprising a base material that includes a surface area of 210-220 m.sup.2 /g, a pore volume of 0.83-0.84 ml/g, a median pore diameter of about 161 Angstroms and an average pore diameter of 150-160 Angstroms and said deposited oxides of catalytic metals include 20-22% total weight WO.sub.3, 2-3% total weight NiO, and 5-6% total weight CoO.
