Abstract: A method for preparing a bulk multi-metallic suitable for hydrotreating heavy oil feeds is provided. In one embodiment of the process of preparing the catalyst precursor which is subsequently sulfided to form the bulk catalyst, a catalyst precursor filter cake is treated with at least a chelating agent, resulting in a catalyst precursor with optimum porosity. In another embodiment, non-agglomerative drying is employed to keep the catalyst precursor from aggregating / clumping. The catalyst precursor obtained herein has an optimum porosity with at least 90% of the pores being macropores and a total pore volume of at least 0.08 g/cc.

The use of the bulk catalyst in hydroprocessing oil feedstock is also provided. The hydroprocessing catalyst has the formula (M t ) a (L u ) b (S v ) d (C w ) e (H x ) f (O y ) g (N z ) h , wherein M is at least one group VIB metal; promoter metal L is optional and if present, L is at least one Group VIII non-noble metal; t, u, v, w, x, y, z representing the total charge for each of the components (M, L, S, C, H, O and N, respectively); t a +u b +v cd +we+x f +yg+z h =0; 0 = b ; and 0 = b / a = 5, ( a + 0.5 b ) a + 2 b ), 0 a + b ), 0 a + b ), 0 g a + b ), 0 a + b ). The catalyst has an X-ray powder diffraction pattern with at least one broad diffraction peak at any of Bragg angles: 8 to 18°, 32 to 40°, and 55 to 65° (from 0 to 70° 2-θ scale). In one embodiment, the catalyst is prepared by sulfiding at least one Group VIB metal compound and optionally at least one group VIII metal compound with a sulfiding agent forming a catalyst precursor; and mixing the catalyst precursor with a hydrocarbon compound to form the hydroprocessing catalyst composition.

Abstract: Disclosed are embodiments relating to a process for treating a hydrocarbon feedstock. In one embodiment with a biologically derived oil as the feedstock, the biologically derived oil feed is deoxygenated by contacting the feed with a metal titanate catalyst having an MTiO3 structure wherein M is a metal having a valence of 2+. In another embodiment with a high acid crude oil as the feedstock, the metal titanate catalyst is employed to reduce the total acid number of the hydrocarbon feed by contacting the feed with the metal titanate catalyst, resulting in a hydrocarbon product having a final total acid number lower than the initial total acid number of the feed. The process can be integrated into conventional refining operations in order to treat refinery feedstreams, whether it is a biofuel source, or a high acid crude.
