Procedure for the improvement of heavy and extra-heavy crudes

摘要

The physical and chemical properties of heavy and extra-heavy crudes are improved by a procedure that uses a homogeneous type catalyst and involves the stages: 1. separation and removal of the water fraction that is contained in the hydrocarbons, 2. catalyst injection and activation of the reaction system, 3. elimination of gaseous hydrocarbons and recovery of the partial pressure of hydrogen at different times, 4. reaction and 5. recovery of distillated products.

主权项

1. A process for the transformation of a heavy and/or extra-heavy crude oil feed into a lighter crude oil, which comprises providing a hydrocarbon feedstock including said crude oil feed to a reaction zone of a reactor, and conducting the following stages comprising
a) separating and removing water from said crude oil feed, b) injecting a liquid phase ionic catalyst into said reaction zone and activating said reaction zone, c) venting said reaction zone to remove gaseous hydrocarbons and introducing hydrogen to said reaction zone to recover partial hydrogen pressure at predetermined intervals, d) reacting said hydrocarbon feedstock under hydrotreating conditions in the reaction zone of the reactor, and e) recovering distillated products.
