Hydroconversion process to upgrade the transport properties of heavy and extra-heavy crude oils at low severity conditions using dispersed-phase catalyst

摘要

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 offshoreUse of operating conditions at low severityReduction of the viscosity and increase of the API gravity at values that allow the transportation by pipeline of heavy or extra-heavy crudeUpgrading of the crude oil properties in a permanent wayHydrocarbon and gases from production centers are used as suppliesOperation in dispersed phase avoiding plugging problemsUse of low-cost disposable catalysts at low concentrations.
