  2. 1. Combustion characteristics of some alternative fuels in ICE: : a detailed numerical study

    Author : Siyuan Hu; Strömningsteknik; []
    Keywords : Combustion; duel fuel; methane; hydrogen; nheptane; methanol; DNS; simulation; openFoam; mixture-averaged; RCCI; ignition wave;

    Abstract : Two major fuels commonly used in compression ignition (CI) and spark ignition (SI) enginesare diesel and gasoline. The reserve of diesel and gasoline is limited, however the combustion ofthese fuels giving rise to air pollution. READ MORE

  4. 2. Caldicellulosiruptor Saccharolyticus: an Ideal Hydrogen Producer?

    Author : Sudhanshu Pawar; Institutionen för kemiteknik; []
    Keywords : Caldicellulosiruptor owensensis; Caldicellulosiruptor saccharolyticus; hydrogen; volumetric hydrogen productivity; biofilm; osmotolerance; wheat straw hydrolysate; evolutionary engineering; CSTR; UA reactor and uracil auxotrophy;

    Abstract : Caldicellulosiruptor saccharolyticus is an extremely thermophilic, strictly anaerobic, Gram-positive and cellulolytic microorganism with a natural ability to produce hydrogen (H2) at nearly theoretical maximum yield, i.e. 4 mol/ mol of glucose. READ MORE

  5. 3. Effects of Varying Combustion Conditions on PCDD/F Formation

    Author : Johanna Aurell; Stellan Marklund; Sukh Sidhu; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; dioxin; formation; PCDD; PCDF; MSW incineration; transient combustion; sulfur; memory effects; quench time; chlorine; combustion; polychlorinated dibenzothiophenes; NO; water; Environmental chemistry; Miljökemi;

    Abstract : Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are by-products emitted from combustion sources such as municipal solid waste (MSW) incineration plants. These organic compounds are recognized as toxic, bioaccumulative and persistent in the environment. READ MORE

  6. 4. Investigation of Emission Characteristics for Diluted Flames and Renewable Fuels in Gas Turbine Combustors

    Author : Fredrik Hermann; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; framdrivningssystem; Motorer; termodynamik; Motors and propulsion systems; Termisk teknik; applied thermodynamics; Thermal engineering; combustor rig experiments; combustor reactor models; synthetic fuel; liquid fuel; gaseous fuel; UHC; CO; NOx; emission measurements; CO2 enriched; humidified combustion; diluted combustion; premixed combustion; Gas turbine; combustion chamber; Energiforskning; Energy research;

    Abstract : Gas turbines have served as economically profitable and reliable generators of power for the past few decades, and have mainly been used in simple and combined cycles. The increased restrictions on hazardous emissions and the increased demand for profitability have created new prospects for innovative power cycles. READ MORE

  7. 5. Hydrogen Production by Integration of Fluidized Bed Heat Exchanger in Steam Reforming of Natural Gas

    Author : Viktor Stenberg; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; 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
