  1. 1. Entrained flow gasification of biomass: soot formation and flame stability

    Författare :Burak Göktepe; Kevin Whitty; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Entrained flow gasification (EFG) is a well-proven, commercially available technology for large scale coal gasification processes, with a production of a high quality syngas (a mixture of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4) and other compounds). For biomass, the process is still under development and there are several hurdles that must be cleared before it can become commercial. LÄS MER

  3. 2. Internal Tar/CH4 Reforming in Biomass Dual Fluidised Bed Gasifiers towards Fuel Synthesis

    Författare :Kristina Göransson; Per Engstrand; Wennan Zhang; Kevin J Whitty; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Allothermal gasification; Bio-automotive fuels; Biomass gasification; Catalytic bed-material; Dual fluidised bed; Ni-catalyst; Syngas cleaning; Tar removal; Tar CH4 reforming;

    Sammanfattning : Production of high-quality syngas from biomass gasification in a dual fluidised bed gasifier (DFBG) has made a significant progress in R&D and Technology demonstration. An S&M scale bio-automotive fuel plant close to the feedstock resources is preferable as biomass feedstock is widely sparse and has relatively low density, low heating value and high moisture content.

  4. 3. Entrained flow studies on biomass fuel powder conversion and ash formation

    Författare :Per Holmgren; Markus Broström; Kentaro Umeki; Rainer Backman; Kevin Whitty; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermochemical biomass conversion; particle image velocimetry; gasification; entrained flow reactor; ash transformation; equilibrium calculations; slag formation;

    Sammanfattning : Reducing the global dependence on fossil fuels is of paramount importance in tackling the environmental challenges we face, not only tomorrow, but already today. Biomass offers a renewable supply of CO2-neutral raw material that can be converted into many different forms of fuels and valuable chemicals, making it a prime candidate for the technologies of tomorrow.

  5. 4. Entrained flow gasification of biomass : On atomisation, transport processes and gasification reactions

    Författare :Mikael Risberg; Kevin Whitty; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Since the energy consumption in the world is increasing together with an increase of greenhouse gas emission it is of importance to find alternatives to fossil fuels. Biomass is one of the alternative energy sources which is both renewable and CO2 neutral. LÄS MER
