Effective Demetalization and Suppression of Coke Formation Using Supercritical Water Technology for Heavy Oil Upgrading
Heavy oil Upgrading Supercritical water
2009/8/4
In this study, a new upgrading method with supercritical water was developed for heavy oil in order to produce light oil that was free from heavy metal and heavy hydrocarbon fraction under coke suppr...
Promotion of Catalytic Activities and Suppression of Deactivation by Water in the Hydrotreatment of Atmospheric Residue
Atmospheric residue Hydrotreating Water addition Hydrodesulfurization
2009/7/24
Water was added to extend the continuous run of the atmospheric residue hydrotreatment process in bench plant and autoclave tests for improvement of catalyst life. Addition of water increased the ca...
Promotion of Catalytic Activity and Suppression of Deactivation by Solvent Addition in the Hydrotreating of Atmospheric Residue
Atmospheric residue Hydrotreating Water addition Hydrodesulfurization
2009/7/24
The effect of addition of several solvents on atmospheric residue (AR) hydrotreating was examined in the autoclave test. Higher hydrodesulfurization (HDS) activity was obtained by adding solvents in t...
