Method for producing low-cost, high volume hydrogen from hydrocarbon sources
1997
A method for the conversion of naturally-occurring or biomass-derived lower to higher hydrocarbon (CXHY, where x may vary from 1-3 and y may vary from 4-8) to low-cost, high-volume hydrogen. In one embodiment, methane, the major component of natural gas, is reacted in a single reaction zone of a mixed-conducting ceramic membrane reactor to form hydrogen via simultaneous partial oxidation and water gas shift reactions at temperatures required for thermal excitations of the mixed-conducting membranes. The hydrogen is produced by catalytically reacting the hydrocarbon with oxygen to form synthesis gas (a mixture of carbon monoxide and hydrogen), followed by a water gas shift (WGS) reaction with steam, wherein both reactions occur in a single reaction zone having a multi-functional catalyst or a combination of catalysts. The hydrogen is separated from other reaction products by membrane-assisted transport or by pressure-swing adsorption technique. Membraneassisted transport may occur via proton transfer or molecular sieving mechanisms.
This paper presents an efficient process to generate hydrogen, using aluminum dross particles activated by mechano-chemical methods and tap water with a pH value ≥ 10.4, obtained by adding of NH 3 aqueous solution 25 wt%/L. The effect of pH value and aluminum amount on hydrogen yield has been studied. For these tests pure aluminium particles and aluminum dross were employed, and SEM analysis was used to study the changes in surface properties of metal occurring due to metal hydrolysis and hydrogen release. The obtained results show that the rate of hydrogen generation increases with the increasing of pH value and aluminum quantity. A hydrogen continuous device was designed and operated. The economical and environmental key aspects associated with the production of hydrogen, using Al dross, are discussed. The data obtained in this research can provide the basis for scale implementation of the aluminum dross hydrolysis process to generate H 2 of high purity (>99.5 vol.%).

Efficient Use of Hydrogen Made by Splitting Water by Reaction with Aluminum Alloy
A new way of improving the country's economy and to decrease the pollution and global warming by the use of hydrogen made by splitting water by reaction with aluminum alloy on demand in cars replacing diesel engine and diesel tank by hydrogen engine and water tank. Today as the need of the petroleum products is increasing with increase in population and industrialization, the depletion of fossil fuels (eg. Petrol, Diesel, Coal etc.) from earth is a harbinger of the energy crisis of the future, so to come out of this problem we find a technology in which we used aluminum which is mixed with some other metals like gallium, indium and tin which splits the water in hydrogen and oxygen. This hydrogen than used as a fuel in vehicles. Now a day's due to fuel depletion the hydrogen produced is used as fuel instead of diesel which will bring the new revolution in the field of this sector. So in future the water will be the only source, which is present abundantly on earth. This technology will help to reduce the usage of fuels and reduce the pollution which also improves the economic condition of the country like India. Solid alloy of aluminum, gallium, indium and tin have been shown to react with water at room temperature to produce hydrogen and aluminum oxide in a exothermic reaction. This aluminum oxide can be recycled into aluminum. Apart from that aluminum metal is abundant on earth. The recycling is less expensive then mining aluminum-containing ore bauxite. After recycling the aluminum oxide back to aluminum 60 times the cost of producing energy would reduce to 10 cents per KW hour or 6.33 per KW hour. ₹ Index Terms-Aluminum, Combustion, Engine and Hydrogen.
Aluminum Hydride, A1H3, as a Hydrogen Storage Compound
2006
Aluminum hydride is a covalent, binary hydride that has been known for more than 60 years and is an attractive medium for on-board automotive hydrogen storage, since it contains 10.1 % by wt. hydrogen with a density of 1.48 g/ml. There are at least 7 non-solvated AlH3 phases, namely a , a ' , 0, y, 6, E and <. The properties of a-AlH3, obtained from the Dow Chemical Co. in 1980, have been previously reported. Here we present a description of the thermodynamic and kinetic properties of freshly prepared a , 0 and y phases of AlH3. In all cases the decomposition kinetics
The Efficiency of Aluminum alloy in Hydrogen production
2024
This study investigates the production of hydrogen gas through water electrolysis using low-cost aluminum electrodes. Aluminum is chosen for its abundance, low cost, and favorable electrochemical properties. The electrolysis process is carried out at varying voltages to monitor the volume of hydrogen gas produced, which is measured by the flow of current through the circuit. The anodic reaction involves the oxidation of aluminum, forming aluminum hydroxide and releasing hydrogen gas, while the cathodic reaction facilitates the reduction of water. Results indicate that different voltages significantly influence the volume of hydrogen gas generated, providing valuable insights into optimizing the efficiency of hydrogen production using aluminum electrodes. This method presents a cost-effective and scalable approach for hydrogen generation, contributing to sustainable energy solutions.
Designing and Analysis of Hydrogen Power Vehicle
The hydrogen powered vehicle works on the Spark Ignition Engine so the vehicle can run with the hydrogen gas along with petrol. A system for generation of hydrogen gas by electrolysis of water for the fueling of an engine is disclosed. The system comprises a power regulator to regulate the flow of an electric current from a battery source to hydrogen generation cell provided in communication with the vehicle engine. The hydrogen generation cell has a positive side and a negative side defined by a partition, each of the positive side and the negative side includes a polarity of electricity conductors. The electricity conductors on the positive side receive the electric current in the hydrogen generation cell, on passing the electric current the water in the water tank undergoes electrolysis to generate oxygen gas at the positive side and hydrogen gas at the negative side, the hydrogen gas is then supplied to the engine via the hydrogen flow path.
Industrial production of light metal hydrides for hydrogen storage
Scripta Materialia, 2007
Light metal hydrides show a high potential for reversible hydrogen storage applications. In view of the potential future storage of large amounts of hydrogen, an economic tonnage scale production will be required. This view point set introduces production methods and discusses the potential for simplifying processing routes and reducing costs in view of an industrial mass production. For this purpose, sodium alanate, for which a cost-competitive production on large scale is considered to be feasible already to date, is used as an example for future promising hydrides like complex hydrides or reactive hydride composites.
