    Abstract: This invention provides a process for forming a solution composition, which process comprises forming a primary solution by bringing together, in an aqueous medium, i) at least one phosphorus compound, ii) at least one Group VI metal compound, iii) at least one Group VIII metal compound, and iv) 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. The molar ratio of additive to the total moles of Group VI metal and Group VIII metal is above 0.30:1, and the atomic ratio of phosphorus to Group VI metal is at least about 0.33:1. Optionally, the primary solution is heated at a temperature above about 40° C. to form a heated solution. The heated solution is optionally cooled to form a cooled solution. Also provided are compositions formed by such processes, processes for forming catalyst compositions from these compositions, and catalyst compositions formed by these processes.

    Abstract: The invention relates to a bulk catalyst comprising at least 60 wt % metal oxidic particles comprising one or more Group VIII metals and Group VIB metal molybdenum, comprising less than 10 mole % of a second Group VIB metal (relative to the total amount of Group VIB metals) and comprising a Group V metal in an amount less than 10 mole % (relative to the total of the Group VIB metals), which bulk catalyst has been calcined at a temperature below a temperature where the hexagonal metastable crystal structure changes to an inactive crystalline structure, preferably below 450° C. and which bulk catalyst has a metastable hexagonal phase characterized by an X-ray diffraction pattern having reflections at 33-35 and 58-61° 2θ. Preferably, the main reflections have a full width at half maximum (FWHM) of less than 2.5. The invention further relates to a process for the manufacture of the bulk catalyst, to the corresponding sulphided bulk catalyst and to the use of said catalyst or sulphided catalyst in the hydroprocessing, in particular the hydrodesulphurisation and hydrodenitrogenation, of a hydrocarbon feedstock.
