Solutions and Catalysts Comprising Group VI Metal, Group VIII Metal, and Phosphorus

A catalyst composition formed by

• I) bringing together a carrier and an impregnation solution, which impregnation solution comprises a Group VI metal, a Group VIII metal, phosphorus, and an additive which is
• a) tetraethylene glycol,
• b) polyethylene glycol having an average molecular weight in the range of about 200 to about 400,
• c) a mixture of tetraethylene glycol and polyethylene glycol having an average molecular weight in the range of about 200 to about 400, or
• d) a mixture of (1) tetraethylene glycol and/or polyethylene glycol having an average molecular weight in the range of about 200 to about 400 and (2) one or more of monoethylene glycol, diethylene glycol, and triethylene glycol,
• where the molar ratio of additive to the total moles of Group VI metal and Group VIII metal is about 0.36:1 to about 0.6:1, and where the atomic ratio of phosphorus to Group VI metal is at least about 0.33:1,
• to form an impregnated carrier;
• and
• II) drying the impregnated carrier, and
• III) optionally calcining the impregnated carrier,
• and optionally sulfiding the catalyst.
