  1. 1. Entrained-Flow Gasification of Black Liquor and Pyrolysis Oil : Experimental and Equilibrium Modelling Studies of Catalytic Co-gasification

    Author : Yawer Jafri; Rikard Gebart; Martin Seemann; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Black liquor; pyrolysis oil; catalytic gasification; co-gasification; gasification; entrained-flow gasification; pilot-scale; Energy Engineering; Energiteknik;

    Abstract : The last couple of decades have seen entrained-flow gasification of black liquor (BL) undergo an incremental process of technical development as an alternative to combustion in a recovery boiler. The ability of the technology to combine chemical recovery with the production of clean syngas renders it a promising candidate for the transformation of chemical pulp mills into integrated forest biorefineries.

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

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

    Abstract : 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. READ MORE

  3. 3. From torrefaction to gasification : Pilot scale studies for upgrading of biomass

    Author : Martin Strandberg; Anders Nordin; Linda Pommer; Jaap Kiel; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; biomass; pilot scale; continuous reactor; grindability; entrained flow gasification; degree of torrefaction; biomass powder;

    Abstract : Increasing the share of biomass, preferably by replacing fossil fuels, is one way to mitigate the present climate change. Fossil coal can be directly replaced by co-combustion of coal and biomass and fossil engine fuels (gasoline and diesel) could potentially partly be replaced by synthetic renewable fuels produced via entrained flow gasification of biomass.

  4. 4. Pressurized entrained flow gasification of pulverized biomass : Experimental characterization of process performance

    Author : Fredrik Weiland; Thomas Kolb; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : The anthropogenic emissions of greenhouse gases (e.g. CO2), mostly connected to the use of fossil fuels, to the atmosphere have increased during the last century and there is significant evidence that this is the main reason for the recent global temperature rise. READ MORE

  5. 5. Refractory corrosion in biomass gasification

    Author : Markus Carlborg; Rainer Backman; Dan Boström; Ragnhild Aune; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory corrosion; slag; biomass; gasification; Materials Science; materialvetenskap;

    Abstract : To stop the net emission of CO2 to the atmosphere, we need to reduce our dependency of fossil fuels. Although a switch to a bio-based feedstock hardly can replace the total amount of fossils used today, utilization of biomass does still have a role in a future in combination with other techniques.
