Abstract: The present invention relates to a catalytic hydroconversion process in dispersed phase of extra-heavy and heavy crude oils for upgrading their transport properties, that operates at low severity conditions, in such a way that the obtained product can be transported by conventional pumping to the distribution and refining centers.The main technical contributions of the hydroconversion process in dispersed phase of this invention to upgrade the transport properties of heavy and extra-heavy crudes are: Compact size and can be localized next to the production facilities on ground or offshore Use of operating conditions at low severity Reduction of the viscosity and increase of the API gravity at values that allow the transportation by pipeline of heavy or extra-heavy crude Upgrading of the crude oil properties in a permanent way Hydrocarbon and gases from production centers are used as supplies Operation in dispersed phase avoiding plugging problems Use of low-cost disposable catalysts at low concentrations.

Abstract: 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.
