Abstract: Methodologies, systems, and devices are disclosed for generating a chemical compound. A reaction chamber holds an amount of a precursor chemical, an activator chamber holds an amount of an activator chemical, and a quenching and neutralizer chamber holds an amount of quenching and neutralizing chemicals. A pump transfers the activator chemical from the activator chamber to the reaction chamber, where the activator chemical reacts with the precursor chemical to form the desired chemical compound. The desired chemical compound is allowed to exit the reaction chamber. Subsequently, the pump transfers the quenching and neutralizing chemicals from the quenching and neutralizer chamber to the reaction chamber, resulting in a quenched and neutralized solution.

Abstract: An ejector has an interior nozzle, an exterior nozzle, a suction part, a mixing part and a diffuser part. The interior nozzle and the exterior nozzle are arranged coaxially with each other. A driving fluid is supplied to the interior nozzle and/or the exterior nozzle. The suction part is arranged on an outer periphery of the exterior nozzle and sucks a suction fluid by a driving fluid jet ejected from the interior nozzle and/or the exterior nozzle. A mixing part mixes the driving fluid jet with the suction fluid, and supplies a mixture fluid. The diffuser part reduces a flow speed of the mixture fluid and ejects the mixture fluid outside. An outlet part of the interior nozzle is arranged at an upstream side of the ejector more than an outlet part of the exterior nozzle along the axial direction of the ejector.

Abstract: A hydrogen production system has an automatic feeding device connected to a buffer tank, and a first valve controlling hydrogen-producing materials to be fed into the buffer tank or not. The buffer tank connects to a main reactor, and the hydrogen-producing materials in the buffer tank are controlled by a second valve to be fed into the main reactor or not. The main reactor connects to a hydrogen storing tank. A one-way check valve is mounted between the main reactor and the hydrogen storing tank to avoid hydrogen in the hydrogen storing tank flowing back to the main reactor. The hydrogen-producing materials in the main reactor undergo a chemical reaction to produce the hydrogen, and the hydrogen storing tank stores the hydrogen to provide fuel of a fuel cell for reducing transporting cost of the hydrogen and for enhancing safety of storing the hydrogen.

Abstract: Provided is a hydrogen water generator that is capable of preventing an increase in pH so as to prevent alkalinization of water while generating water containing plenty of hydrogen gas. A hydrogen water generator includes a container having water and magnesium particles, capable of reacting with the water to generate hydrogen gas, encapsulated therein, wherein the container is made of an air-permeable and water-impermeable material, which allows the hydrogen gas to pass from the inside to the outside of the container and prevents the water from passing from the inside to the outside of the container. At least one kind of thermoplastic resin selected from a group consisting of polyvinylidene chloride, polyvinyl chloride, and polyacrylonitrile may be used as the air-permeable and water-impermeable material.

Abstract: The invention relates to compact and lightweight disposable accumulators for generating electric energy with extremely high energy densities (>1 kWh/kg and >k Wh/liter), which are of immense interest in many areas of application. One possibility for implementing such energy accumulators consists in using metal hydrides in hydrogen generators in which hydrogen is generated by hydrolytically splitting off a proton from water in conjunction with the metal hydride. The chemical energy stored in the hydrogen can then be converted into electric energy in a fuel cell in a second step. Only half of the generated hydrogen originates from the metal hydride during the hydrolysis reaction; the water used for the hydrolysis process supplies the other half.

Abstract: A method of and apparatus for desalinating sea water using geothermal energy. A low voltage (such as less than 0.9V) is applied to a hydrogen generating catalysts to generate hydrogen and oxygen, wherein geothermal heat is used as a heat source. The hydrogen and oxygen are used to drive a gas turbine to generate electricity. The oxygen and hydrogen are transported away and combusted to generate heat and pure water, as such salt are separated from the pure water.

Abstract: The present disclosure is directed to steam reformers for the production of a hydrogen rich reformate, comprising a shell having a first end, a second end, and a passage extending generally between the first end and the second end of the shell, and at least one heat source disposed about the second end of the shell. The shell comprises at least one conduit member comprising at least one thermally emissive and high radiant emissivity material, at least partially disposed within the shell cavity. The shell further comprises at least one reactor module at least a portion of which is disposed within the shell cavity and about the at least one conduit member and comprises at least one reforming catalyst. The disclosure is also directed to methods of producing a hydrogen reformate utilizing the steam reformers, comprising the steps of combusting a combustible mixture in a burner to produce a combustion exhaust that interacts with the steam reactor module(s) through surface to surface radiation and convection heat transfer, and reforming a hydrocarbon fuel mixed with steam in the steam reformers to produce a hydrogen-containing reformate. The present disclosure is further directed to reactor modules for use with the above steam reformers and methods of producing a hydrogen reformate.

Each metal oxide of a catalyst structure includes nickel and/or aluminum, where one or more metal oxides includes a nickel aluminum oxide, and the one or more nickel aluminum oxides is greater than 50% by weight of the catalyst structure. The catalyst structures further have surface areas of at least 13 m2/g. The catalyst structures are resistant to high concentrations of sulfur and are effective in reforming operations for converting methane and other light hydrocarbons to hydrogen and one or more other components. For example, the catalyst structures are effective in coal and biomass gasification systems for the forming and cleanup of synthetic gas.
