The present invention relates to a process for the partial upgrading of properties of heavy and/or extra-heavy crude oil by low severity catalytic hydrotreatment in only one reaction step. The process of the present invention is obtained upgraded oil with properties required for its transportation from offshore platforms either to maritime terminal or to refining centers. The process reduces the viscosity of heavy and/or extra-heavy crude oil, and decreases the concentration of impurities, such as sulfur, nitrogen, and metals, in such a way that heavy and/or extra-heavy crude oils can be transported to maritime terminals or to refining centers. The process increases the lifetime of the catalyst and decreased operating costs by reducing consumption of utilities because the operation of the process is carried out at lower severity. The partially upgraded oils obtained in this process can be transported directly to the maritime terminals or to existing refineries.

Process for partial upgrading of heavy and/or extra-heavy crude oils for transportation

A process for hydroconversion-distillation of heavy and/or extra-heavy crude oils, which comprises four stages:

Process of hydroconversion-distillation of heavy and/or extra-heavy crude oils

A supported carbon having high surface area, high pore volume containing (i) molybdenum (ii) a metal of non noble Group VIII, (iii) phosphorous, is used for hydrometallization of heavy crude oil and residue. The catalyst contains about 6 to 15 wt % molybdenum as MoO, about 1 to 6 wt % cobalt or nickel as CoO or NiO and phosphorus as phosphorous oxide. One characteristic of the catalyst is the portion of pores having pore diameter in the range of 200 to 2000 Angstrom of 20 percent or more. The catalyst prepared by chelating agent has higher hydrodesulfurization activity assuming that more dispersed active metals are present on this catalyst. Long run activity studies show that catalyst having only molybdenum supported on activated carbon has good stability with time-on-stream and very high metal retention capacity.

Carbon supported catalyst for demetallation of heavy crude oil and residue

A catalyst for hydrotreating, especially hydrodesulfurization, of residua and heavy crudes is prepared by synthesizing the support from titanium and boehmite, to form either a titanium/alumina support (TiO/AlO) or a titanium-alumina support (TiO&#x2014;AlO) that is thereafter provided with at least one hydrogenating metal from group VIB in oxide form and a promoter from group VIII also in oxide form. The (TiO/AlO) support is prepared from boehmite, which is peptized by using an inorganic acid, then extruded, calcined and impregnated with a solution containing titanium, while the (TiO&#x2014;AlO) support is prepared by admixing boehmite with a titanium-containing solution, peptized using an inorganic acid, extruded and calcined to obtain the titanium-alumina support.
