  • Patent number: 9464239
    Abstract: The present invention relates to improving heavy crude oil, and extra through a scheme considering the use of ionic liquids catalysts based on Mo and Fe catalyst is highly miscible with crude oil and are in the homogeneous phase crude oil. Furthermore, this invention relates to improving heavy crude in two stages, the first ionic liquid catalyst, and the second supported catalyst. The API gravity crude is increased from 12.5 to 19 points in the first stage and viscosities up to 5600-1600 decreased from 60-40 cSt certain to 37.8° C. While in the second stage, you get an upgraded crude oil with 32.9° API, viscosity of 4.0 cSt, reduction in total sulphur content of 0.85 wt % nitrogen and 0295 ppm by weight, respectively. As a considerable reduction of asphaltenes from 28.65 to 3.7% weight.

  • Publication number: 20120318714
    Abstract: Heavy crude oil residue and vacuum residue is upgraded using an ionic liquid catalyst formulated with metals of Group VIB and VIIIB of the periodic table, which catalyst is highly miscible in the hydrocarbon phase. The combination of different metals and acidity from the protons that make up the ionic liquid breaks the links C—S, C—N and C—O of the resins and asphaltenes and increases API gravity, decreases viscosity, removes sulfur and nitrogen compounds, and results in conversion of 50 to 70% of the waste oil and heavy crude oil into lighter distillates.
