Abstract
A process is disclosed for the demetalation of organically-bound compounds of Group VIII metals, particularly iron, from hydrocarbonaceous feedstock. In the process, an aqueous solution of amino-carboxylic acid, or salts, particularly EDTA, is used to form complexes with the metals and extract them from the feedstock. The aqueous phase containing the complexed metals contaminants is then separated from the hydrocarbonaceous phase.
