Demetallization of heavy oils

Patent ·
OSTI ID:6927240
;
An improved process for removing metals from heavy oils and other hydrocarbon feed streams is disclosed. The process includes adding phosphorus sulfide to the hydrocarbon feed stream under suitable demetallizing conditions. It is believed that phosphorus sulfide reacts with the metals contained in the hydrocarbon containing feed stream to form oil insoluble compounds that can be removed from the hydrocarbon containing feed stream by any conventional method, such as filtration, centrifugation, or decantation.
