  • Bio4Energy Scientists Make First-ever Bio-based Equivalent of Carbon Black from Pyrolysis Oil

    Magnus Marklund B4E RISE ETCMagnus Marklund, CEO at RISE Energy Technology Center, shows a sample of the "green" Black Carbon developed by his team in Bio4Energy and at RISE. Bio4Energy© 2018.Scientists in Bio4Energy have succeeded in making a bio-based equivalent of Carbon Black, one of the most widely used carbon-based industrial chemicals. Carbon Black forms when certain heavy petroleum products are incompletely burned, and there is an established process for making Carbon Black from fossil oil products in the petrochemical industry. The International Agency for Research on Cancer states that this material, which takes the form of a colloid, could “possibly” induce cancer and cause respiratory problems in humans. 

    To the best of the Bio4Energy scientists' knowledge, the "green" equivalent of Carbon Black they have made is the first ever to be developed from pyrolysis oil.

    In fact, the researchers at RISE Energy Technology Centre (RISE ETC), at Piteå, Sweden—part of the platform Bio4Energy Thermochemical Conversion Technologies—used pyrolysis oil made from renewable solid biomass in a high-temperature process developed in-house.

    In experiments mimicking the petrochemical industry’s main production process for making Carbon Black, they sprayed pyrolysis oil into a reactor at high temperatures and the resulting material—that is, the “green” Carbon Black—was separated from the gaseous stream at cooling.

  • Bio4Energy-funded Projects Promoting Excellence, Collaboration Focus of Event

    Audience 210518 2 420Twice a year, the Bio4Energy scientists meet as a group to exchange ideas. Photo by Bio4Energy (archives).Bio4Energy offers its scientists the possibility to apply for so-called Strategic Funds to finance projects on new lines of research that are likely to advance the frontiers of science. The projects also have to promote collaboration between researchers from different disciplines or organisations; including universities, institutes and industry tied to the research environment.

    Today’s Bio4Energy Researchers’ Meeting, a biannual event for the research programme within the environment, learnt about projects enabled by those funds.

  • Conference on the Impact of Fuel Quality on Power Production and the Environment

    Call for papers - 28th International Conference Impacts of Fuel Quality on Power Production and the Environment

    cropped Final Logo
    When: Postponed until late September 2021

    Where: Åre, Sweden


    This conference, 28th in the series, will highlight solutions to the significant fuel-quality challenges facing power producers using current power technologies such as fluidised bed, sub-critical boilers, incineration, as well as newer technologies such as IGCC, PFBC, super- and ultra-super-critical boilers, oxy-fuel systems and gasifiers. These challenges involve fuel preparation and blending, slagging, fouling, corrosion, aerosol formation, ash disposal, catalyst poisoning, availability and capacity, as well as sensors and control strategies.

    The conference emphasises end-results and application of fundamental information to minimise fuel quality impacts on power
    production and the environment. The conference will focus on traditional fuels, particularly traded coals, low-grade and low-rank coals and opportunity fuels such as biomass, tires, black liquor, MSW, waste sludge and pet coke. Fundamental studies, pilot-scale investigations, full-scale evaluations and computer simulation papers are encouraged.

    Sessions for the conference will include, but are not limited toBio4energy cmyk
