Abstract
A method for upgrading a heavy oil includes: disposing a catalyst comprising rhodium and a support in a heavy oil environment, the heavy oil environment including a heavy oil comprising an aromatic compound; introducing hydrogen; and hydrogenating the aromatic compound with the catalyst and hydrogen to upgrade the heavy oil to upgraded oil. A method for converting an asphaltene includes: disposing a supported catalyst in a composition comprising an asphaltene, the supported catalyst being a low temperature catalyst; introducing hydrogen; and hydrogenating the asphaltene to convert the asphaltene into a hydrogenated asphaltene.
Claims32
A method for upgrading a heavy oil, the method comprising:
- disposing a catalyst comprising rhodium and a support in a heavy oil environment, the heavy oil environment including a heavy oil comprising an aromatic compound;
- introducing hydrogen;
- and
