Abstract
An improved process for removing metals from heavy oils and other hydrocarbon feed streams is disclosed. The process includes adding elemental phosphorus to the hydrocarbon feed stream under suitable demetallizing conditions. It is believed that elemental phosphorus 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.
