Embodiments of the disclosure provide an aqueous reforming system and a method for upgrading heavy hydrocarbons. A hydrocarbon feed and a surfactant stream are combined to produce a first precursor stream. The first precursor stream and an alkali feed are combined to produce a second precursor stream. The second precursor stream and a transition metal feed are combined to produce a catalytic emulsion stream. The catalytic emulsion stream is heated to produce a catalytic suspension and a decomposition gas, where the decomposition gas is separated by a first separator. The catalytic suspension is combined with a preheated water stream to produce an aqueous reformer feed. The aqueous reformer feed is introduced to an aqueous reformer such that the heavy hydrocarbons undergo conversion reactions to produce an effluent stream. The effluent stream is introduced to a second separator to produce a heavy stream and a light stream. The light stream is introduced to a third separator to produce a gas stream, a distillate stream, and a spent water stream. Optionally, a portion of the distillate stream and the hydrocarbon feed can be combined to produce the first precursor stream such that the first precursor stream is in the absence of a surfactant.
