Method for demetallating petroleum streams |
| abstract |
The present invention relates to a process for demetallating a petroleum stream by contacting a metals-containing petroleum feed in the presence of an aqueous base selected from Group IA and IIA hydroxides and carbonates and ammonium hydroxide and carbonate and mixtures thereof, an oxygen containing gas and a phase transfer agent at a temperature of up to 180 °C for a time sufficient to produce a treated petroleum feed having a decreased metals content. The invention provides a method for enhancing the value of petroleum feeds that traditionally have limited use in refineries due to their metals, e.g., Ni and V content. |
