Evaluation of Hydrogen Production System with High Temperature Gas-cooled Reactor Masuro Ogawa* and Shusaku Shiozawa Department of Advanced Nuclear Heat Technology Japan Atomic Energy Research Institute Oarai Ibaraki 311-1394 Japan The present paper describes hydrogen demand energy flux of various energies thermal The hydrogen economy is getting higher visibility and stronger political support in several parts of the world In recent years the scope of the International Atomic Energy Agency (IAEA) program on non-electric applications of nuclear energy has been widened to include other more promising applications such as nuclear hydrogen production and high temperature process heat

Hydrogen Production Technologies: Current State and Future

Addition of steam and/or oxygen in the gasification process results in the production of "syngas" with a H 2 /CO ratio of 2/1 the latter used as feedstock to a Fischer-Tropsch reactor to make higher hydrocarbons (synthetic gasoline and diesel) or to a WGS reactor for hydrogen production

Hydrogen (H 2 ) is currently used mainly in the chemical industry for the production of ammonia and methanol Nevertheless in the near future hydrogen is expected to become a significant fuel that will largely contribute to the quality of atmospheric air Hydrogen as a chemical element (H) is the most widespread one on the earth and as molecular dihydrogen (Hsub2/sub) can

Hydrogen - Hydrogen - Production and applications of hydrogen: The most important industrial method for the production of hydrogen is the catalytic steam–hydrocarbon process in which gaseous or vaporized hydrocarbons are treated with steam at high pressure over a nickel catalyst at 650–950 C to produce carbon oxides and hydrogen


Hydrogen production using high temperature nuclear reactors

reactor concept and its potential to be used in certain hydrogen niche markets The work covers the production storage distribution and use of hydrogen as a fuel for vehicles and aviation and as chemical feedstock for the oil refining and ammonia production industry The study indicates that HTRs may be suitable for hydrogen production under

MODELING OF BIOMASS PYROLYSIS FOR HYDROGEN PRODUCTION: THE FLUIDIZED BED REACTOR Danny Lathouwers and Josette Bellan Jet Propulsion Laboratory California Institute of Technology Pasadena CA 91108-8099 Abstract A numerical study is performed in order to evaluate the performance and optimal operating condi-

(Page 1) Steam reforming of natural gas at petroleum refining facilities is the predominant means of producing hydrogen in the chemical process industries (CPI) Because hydrogen needs within various sectors of the CPI are at their highest levels in history and are continuing to grow an understanding of this method of hydrogen production and purification can be useful

Although most of the world's hydrogen production today is being produced through a more CO2 intensive process called Steam Methane Reforming (SMR) hydrogen can also be produced through a process that makes use of renewable electricity leading to the production of "green" or CO2 neutral hydrogen

21 12 2005Hydrogen yielding species of cyanobacteria Cyanobacteria form a large and diverse group of oxygenic photoautotrophic prokaryotes many of which have the ability to produce hydrogen (Table (Table1) 1) Hydrogen production has been studied in a very wide variety of cyanobacterial species and strains

Full Article Biological Hydrogen Production from Starch Wastewater Using a Novel Up-flow Anaerobic Staged Reactor Mahmoud Nasr a * Ahmed Tawfik a Shinichi Ookawara a b and Masaaki Suzuki a b Continuous and batch tests were conducted to evaluate fermentative biohydrogen production from starch wastewater via a mesophillic up-flow anaerobic staged reactor

Large-scale production of hydrogen through steam reforming directly produces CO2 as a side product In addition the heating of reactors through fossil-fuel burning contributes further CO2 emissions One problem is that the catalyst bed is heated unevenly which renders much of the catalyst effectively inactive Wismann et al describe an electrical heating scheme for a metal tube reactor

This paper will deal with large scale hydrogen production in stationary plants using steam reforming Steam Reforming for Hydrogen Production Reforming reactions The principal process for converting hydrocarbons into hydrogen is steam reforming [6 7] which involves the following reactions: CH4 + H2O = CO + 3H2 (-ΔH o 298 = -206 kJ/mol) (1)

Hydrogen production by plasma electrolysis reactor of

The optimum hydrogen production was 50 71 mmol/min obtained at 700 V with 0 03 M KOH 10% vol ethanol and 6 6 cm cathode deep with energy consumption 1 49 kJ/mmol The result demonstrates a promising path for hydrogen production by utilizing plasma electrolysis reactor

Hydrogen production by water dissociation using mixed conducting membranes 201 Matthew B Richards Arkal S Shenoy Kenneth R Schultz Coupling the modular helium reactor to hydrogen production processes 203 SESSION IV 217 Samim Anghaie and Blair Smith Hydrogen production with fully integrated fuel cycle gas and vapour core reactors 219

The main purpose of this work is to present an experimental operating analysis of a silica membrane reactor (MR) for hydrogen production during the methanol steam reforming (MSR) reaction To implement this performance analysis a microporous silica membrane is synthesized by a polymeric sol–gel method To achieve

Today 95% of hydrogen is produced either from wood or from fossil fuels such as natural gas and oil Three types of production process are currently in use: The most common hydrogen production process is natural gas reforming — sometimes called steam methane reforming because it uses high-temperature steam

A method for making hydrogen from methane without emitting carbon dioxide could be a new route to a sustainable future for fossil fuels Chemists and engineers at the University of California Santa Barbara (UCSB) in the US bubble methane through a molten bismuth–nickel catalyst converting 95% of the gas into graphite and hydrogen

information exchange meeting on the "Nuclear Production of Hydrogen" at Argonne National Laboratory in the United States on 2-3 October 2003 The main objective of the meeting was to review recent scientific and technical developments in the field since the first meeting held at OECD headquarters in Paris France in October 2000

Construct a solar hydrogen production demonstration plant in the 750 kWth range to verify the developed technologies for solar H2O splitting Operate the plant and demonstrate hydrogen production and storage on site (at levels 3 kg/week) Perform a detailed techno-economic study for the commercial exploitation of the solar process External
