Magnus 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.
