This technology is well developed and available commercially, and systems that can efficiently use intermittent renewable power are being developed. 3 Left: Gas flow characteristics of 5 representative reductions. Hydrane Single stage non catalytic hydro gasification 3,500 6. Interestingly, samples a and b did not reveal any signs of solid carbon, although the analysis of the mass balance of the cyclic experiments strongly indicated that a significant amount of carbon is deposited during the reduction.
Hydrogen Energy, 2011, 6, 1—8. also called steam methane reforming or SMR• Water H 2O can also be split into hydrogen H 2 and oxygen O 2 using electrolysis or solar energy.
The extended purge phase with nitrogen and possibly structural changes in the oxidation carrier by the cooling down phase completely remove CO 2 residues, thus decrease the overall CO 2 concentration. It is therefore important to measure the sintering temperature of the mineral matter content of the coal being used in the gasifier.

Thermochemical Processes Some thermal processes use the energy in various resources, such as natural gas, coal, or biomass, to release hydrogen from their molecular structure. An explanation for this is the duration of the sweeping phase between the reduction and oxidation with nitrogen. Erosive wear problems associated with abrasive materials are also significantly reduced with this type of system.
shows the pressure profile and the gas flow adjustment of two representative pressurised oxidations. The reformer steam-iron process combines the conventional steam reforming with the steam-iron process. 4 Representative pressure oxidations performed with 0. - Decentralised production logistics to reduce hydrogen transport and storage demand. At this chemical looping process a solid contact mass that consists of magnetite Fe 3O 4 is reduced by hydrogen and carbon monoxide which is produced at the reforming process 4.
The surface of the oxygen carrier was analysed by scanning electron microscopy SEM Zeiss Ultra 55, acceleration voltage 15 kV. The work has shown that chemical looping water splitting is suitable for the direct production of pressurised hydrogen using hydrocarbons as feed.
The Koppers process can only use oxygen.
At Graz University of Technology the reformer steam iron process is developed as a scalable, on-site process, to emphasize on the requirements of natural resources.
However, slurries commonly made with moisture suffer a loss of efficiency due to the vaporization of a substantial amounts of water.
