The present disclosure is directed to a byproduct recovery system used in conjunction with a hydrogen production system. The hydrogen production system creates hydrogen gas and a byproduct through a chemical reaction. The byproduct of this chemical reaction is then contained within a solution which was part of the chemical reaction. The solution flows from the hydrogen production system into a recovery chamber. Within the recovery chamber the byproduct of the chemical reaction is removed from the solution. The byproduct may then be stored or transported to another outside system remote from both the hydrogen production system and the byproduct recovery system.

A method for obtaining aluminum-containing nanoparticles is provided. The method includes exposing at least one surface comprising aluminum to an alkaline aqueous solution. The method further includes exposing the at least one surface to electro-hydraulic shock waves and an electron flux. The at least one surface undergoes electro-erosion which creates alumina-hydrated nanoparticles having a negative surface electrical charge. The method further includes transforming the alumina-hydrated nanoparticles into aquachelate nanoparticles by attaching water molecules to the alumina-hydrated nanoparticles.

The present invention relates to a method for preparing metal oxide nanoparticles and metal oxide nanoparticles prepared thereby. The method includes: dipping a cathode and an anode formed of a metal for forming oxide, in an inorganic electrolyte solution containing halogen salt, and applying voltage to the anode and the cathode to form, on the anode, metal oxide forming an anode surface. According to a method of the present invention, disadvantages of typical nanoparticle synthesizing methods may be solved to cheaply and rapidly manufacture nanoparticles having various structures through a single process without using a surfactant. In practicing a method of the invention, metal oxide nanoparticles may be rapidly formed, nanoparticles having excellent crystallinity may be produced, and factors of the anodizing method, such as voltage, temperature, an electrolyte, and an electrolyte concentration may be changed to simply adjust a shape of the nanoparticles.

The present invention is directed to hydrogen production systems and methods of using same. The systems support a hydrogen production reaction that comprises aluminum and a catalyst or wool and van produce hydrogen on-demand. The hydrogen and the heat produced by the systems can be used for many applications, including to power vehicles, heat homes, or power electricity-producing power plants.

The subject of the present invention is a method for processing metallized packaging materials, especially beverage cartons, or blister packaging. According to the invention, the aluminum is dissolved with the aid of acid and separated from the plastic. The metal-containing acid solution then undergoes pyrohydrolytic treatment and the acid is thus recovered. The aluminum can be recovered as valuable aluminum oxide.
