  2. 1. Hydrogen Production by Integration of Fluidized Bed Heat Exchanger in Steam Reforming of Natural Gas

    Author : Viktor Stenberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BECCS; Steam reforming; CCS; Hydrogen; fluidized bed heat exchanger; Oxygen carrier aided combustion; chemical-looping combustion;

    Abstract : The possibility to integrate fluidized beds as heat sources for steam reforming in hydrogen production plants is examined in this work. Sites with large-scale production and consumption of hydrogen such as refineries are considered as especially interesting. READ MORE

  4. 2. Hydrogen Production by Integration of Fluidized Bed Heat Exchangers in Steam Reforming

    Author : Viktor Stenberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; oxygen carrier aided combustion; chemical-looping combustion; bed-to-tube heat transfer.; steam reforming; fluidized bed heat exchanger;

    Abstract : The possibility to integrate fluidized beds as heat sources for steam reforming in industrial hydrogen production plants is examined in this work. The proposed processes include traditional catalytic steam reforming of natural gas (SMR), shift reactors and purification steps; the main difference is the reformer furnace. READ MORE

  5. 3. Methanation of biosyngas in a fluidized bed reactor

    Author : Martin Seemann; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENERGY TECHNOLOGY; REGENERATIVE ENERGIES; GASIFICATION OF WOOD; FLUIDIZED BED PROCESSES; CHEMICAL ENGINEERING; FUEL TECHNOLOGY; ALTERNATIVE ENERGIES; METHANATION OF HYDROGEN-CARBONMONOXIDE MIXTURES; SYNTHETIC FUELS; NATURAL GAS; BIOGASES;

    Abstract : Rising prices for fossil fuels and concerns over the climate change increase the interest in renewable energies. Synthetic natural gas (SNG) can be an option, filling the request for alternatives in the transportation sector, where the dependence on the oil is very strong. READ MORE

  6. 4. Energy Efficient Processes for the Production of Gaseous Biofuels - Reforming and Gas Upgrading

    Author : Helena Svensson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofuels; Reverse-flow reforming; Gas upgrading; Amine absorption;

    Abstract : Replacing fossil fuels with biofuels is one way of reducing the emission of greenhouse gases into the atmosphere, thus decreasing our impact on the global climate. For this to be a viable option, several production routes are needed, as no single option can fully replace fossil fuels. READ MORE

  7. 5. Syngas production by integrating thermal conversion processes in an existing biorefinery

    Author : Katarina Åberg; Anders Nordin; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; biofuels; syngas; gasification; torrefaction; methane reforming; H2 CO ratio; system analysis; CO2 negativity;

    Abstract : The use of carbon from fossil-based resources result in changes in the earth’s climate due to emissions of greenhouse gases. Biomass is the only renewable source of carbon that may be converted to transportation fuels and chemicals, markets now fully dominated by traditional oil supply. READ MORE
