Feasibility of solar thermochemical natural gas desulphurization and hydrogen generation with a membrane reactor

Thermochemical solar hydrogen generation.

Solar direct, indirect and hybrid thermochemical processes are presented for the generation of hydrogen and compared to alternate solar hydrogen processes. A hybrid solar thermal/electrochemical process combines efficient photovoltaics and concentrated excess sub-bandgap heat into highly efficient elevated temperature solar electrolysis of water and generation of H2 fuel utilizing the thermodyn...

Investigation of Sour Natural Gas Decomposition in a Nozzle-type Solar Reactor for Hydrogen Production

Efficient production of hydrogen from natural gas steam reforming in palladium membrane reactor

Ultra-thin, high performance composite palladium membrane, developed via a novel electroless plating method, was applied to construct a membrane reactor for methane steam reforming reaction, which was investigated under the following working conditions: temperature 723–823 K, pressure 300–900 kPa, gas hourly space velocity (GHSV) 4000–8000 mL g 1 cat h , steam-to-carbon feed ratio (S/C, mol/mol...

Thermochemical hydrogen generation: heat requirements and costs.

We are pleased that Dagan et al. have found an earlier reference (1) than Reiss (2), whom we cited (3), on the production of alternating single impulses in a network of model neurons. The general properties of reciprocally inhibitory neuronal networks are discussed by Sherrington (4), who in turn cites a number of 19th-century examples of similar alternating behaviors, both experimental and the...

IV.A.11 Ceramic Membrane Reactor Systems for Converting Natural Gas to Hydrogen and Synthesis Gas (ITM Syngas)

• Research, develop and demonstrate the Ion Transport Membrane (ITM) Syngas ceramic membrane reactor system for the low-cost conversion of natural gas to hydrogen and synthesis gas. • Scale-up the ITM Syngas reactor technology through three levels of pilot-scale testing and precommercial demonstration. • Obtain the technical, engineering, operating and economic data necessary for the final step...
