Abstract
Metals contained in a hydrocarbon containing feed stream are removed by contacting the hydrocarbon containing feed stream with a phosphorous compound selected from the group consisting of phosphine, hydrocarbylphosphines, hydrocarbylphosphites, hydrocarbylphosphonates, hydrocarbylphosphates, hydrocarbylphosphine oxides, hydrocarbylthiophosphites, and hydrocarbylphosphine sulfides to convert the metals to oil insoluble compounds which can be removed from the hydrocarbon containing feed stream by conventional methods.
Claims10
A process for removing metals contained in a hydrocarbon containing feed stream comprising the steps of:
- contacting said hydrocarbon containing feed stream under suitable demetallization conditions with a phosphorus compound selected from the group consisting of phosphine, hydrocarbylphosphines, hydrocarbylphosphites, hydrocarbylphosphonates, hydrocarbylphosphates, hydrocarbylphosphine oxides, hydrocarbylthiophosphites, and hydrocarbylphosphine sulfides to convert said metals to oil insoluble compounds;
- and
- removing said oil insoluble compounds of said metals from said hydrocarbon containing feed stream in the absence of a cracking catalyst.
