thermal conversion

  • Bio4Energy Researchers Acknowledged for 'Milestone' Article on Ash Transformation Chemistry

    NS MOh DB MB ChB AS8617For a long time, the selection of fuels for biomass combustion, in terms of avoiding problems such as slagging and fouling of the reactors, often was carried out based on trial and error. About a decade into the 21st century, a group of Sweden-based researchers with long-standing experience in high-temperature conversion of woody feedstock to heat and power started to mull over a more systematic approach to assessing the reactions in thermal conversion of the chief trouble-making content of the biomass: the inorganic compounds forming the ash.

    In 2012, the scientist, brought together under the umbrella of Bio4Energy, published an article on Ash Transformation Chemistry during Combustion of Biomass in the interdisciplinary scientific journal Energy & Fuels by the American Chemical Society (ASC). The article describes a conceptual model by which any type of biomass—whether originating from wood, woody or agricultural residue or other types of combustible waste—may be characterised, and thus understood, in terms of the basic chemical reactions that take place during thermal conversion of biomass into heat, power, fuels and chemicals.

    After having been amply cited by other researchers around the world, this spring, the article by Bio4Energy scientists received the 2017 Energy & Fuels Joint Award for Excellence in Publication.

  • Gasification 2017, Helsinki, Finland

    ACI’s 6th Annual Gasification Summit, taking place on 15-16 March 2017 in Helsinki, Finland. The conference will comprise two days of formal presentations, interactive roundtable discussions and excellent networking opportunities. The event will be providing an ideal setting to convene with your peers to discuss both current operational & future planned gasification plants, end product markets, potential barriers & support policies as well as project economics & finance.

    Agenda Committee:
    • Thomas von Kossak, Shell
    • Alison Kerester, The Gasification And Syngas Technologies Council
    • Juhani Isaksson, Valmet
    • Reinhard Rauch, Bioenergy 2020+

    Exclusive Lahti Energy’s Kymijärvi II power plant Site Visit – Tuesday 14th March 2017

    During the afternoon of 14th of March 2017 up to 40 conference attendees will receive a unique opportunity to visit Lahti Energy’s Kymijärvi II power plant. Kymijärvi II is the world’s first gasification plant that utilizes solid recovered fuel (SRF). At the 160 MW plant, waste-derived fuel is gasified, the gas is cooled down and cleaned, and the clean gas is then burned in the boiler.

    There is no extra charge to attend the site visit, but spaces are limited and allocated on a first come first served basis. Please register your attendance for the site visit when booking for the conference.
  • Thermal Treatment to Be Tested for Turning Waste to Resource on Space Trip - Video, Audio

    A Bio4Energy scientist at Umeå University (UmU) has won funds for conducting research that will feed into a Trash to Gas initiative started in 2012 by the U.S. National Aeronautics and Space Administration, and which will be stepped up in connection with the preparations of NASA astronauts' first-ever manned trip to the planet Mars in the 2030s. The trip to outer space is longer and further from Earth than any of NASA's previous manned trips and implies new challenges when it comes to handling and disposal of waste such as used garments and towels, spent food packaging, human waste and paper products. Notably, whatever is leftover cannot be smelly, nor bulky and, ideally, should be recycled for re-use.

    Researchers at NASA's Kennedy Space Center have built a prototype reactor
    designed to make something useful from the trash astronauts accumulate in space.
    The device incinerates garbage to produce methane, oxygen and water--which can
    be used for rocket fuel, breathing air and for life support. Original video clip and
    report by George Diller posted on Youtube, 20 March 2013.
