ABSTRACT:
A process is disclosed for removing metals contaminants, particularly calcium compounds, from hydrocarbonaceous feedstocks using aqueous carbonic acids, its salts, or mixtures thereof as the metals extraction agent. The hydrocarbonaceous layer and aqueous layers are then separated and the demetalated hydrocarbonaceous feedstock is removed for further processing.
