  • Ionic liquid catalyst for improvement of heavy and extra heavy crude
    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.
