    Abstract: A process for re-refining used lubricating oil (ULO), much of which is used motor oil (UMO) relies on more rapid heating, turbulent flows, higher peak temperatures, to achieve rapid thermal cracking, even including metal-bearing additives without catalysts, compared to conventional refining of crude oil and conventional recycling processing of UMO. By thermally cracking this way and scrubbing with recycled, processed liquids from the flow stream, a process readily removes metal-bearing hydrocarbons in typical lubricating oil additives. Those bonded metals consigned to heavy fraction "bottoms," are commonly non- removable by other recycling schemes. Long chain polymers including paraffins are broken into lighter hydrocarbons with properties typical of fuels containing olefins, naphthenes, and the like. Data and analysis reveal low solids, effective metal removal, comparatively low viscosity and boiling points, and greatly reduced sulfur content in fuel and oil products resulting.

    Abstract: 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.

    Abstract: Plastic waste (2) is picked up from the water surface in place of its naturally created accumulation point; it is desalinated and/or demoisturized directly in the vessel (1 ) and subsequently it is depolymerized in the vessel (1 ) without the access of the air. The resulting vapors are distilled, whereby, for example, at least one diesel fraction is separated and it is subsequently purified and offered as a fuel for maritime transport, that is, mainly for ships outside the system of plastic waste (2) processing. At least one vessel (1) sailing at the sea in the vicinity of the accumulation point of the plastic waste (2) has a mean (3) for picking up the plastic waste (2) from the water surface, the device for desalination and/or demoisturization of the plastic waste, and it also has at least one depolymerization unit (4) for depolymerization of the plastic waste (2) without the access of the air, the distillation unit for separation of at least one diesel fraction, the device for purification of the diesel fraction and a gas station (5) for dispensing of the purified diesel fraction as a fuel for the maritime transport. The device for purification of at least one fraction uses a hydrogenation process.
