About KTH

Since its founding in 1827, KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. KTH is Sweden’s largest technical university and accounts for over one third of the national capacity for engineering studies and technical research at post-secondary level. KTH has over 12000 undergraduate students, 1800 active postgraduate students and a staff of 3600.

Energy is one of five research platforms at the university, with 450 researchers, 48 research groups, and 15 research centres involved in a broad span of projects and education. Biomass, and in particular thermochemical conversion, plays a prominent role in these endeavours. Chemical Technology, Energy and Furnace, and Heat and Power Technology are the three divisions involved in BRISK2 project. Each division collaborate both within several academic research programmes and industries.

 Research Focus:

  • Polygeneration
  • Membrane distillation
  • Catalyst development for pyrolysis with aiming at producing transportation fuel
  • Biomass/waste pyrolysis/ gasification
  • Catalytic process for gas upgrading
  • Gas cleaning

In the BRISK2 initiative, KTH has opened up key facilities in biofuels research, with an emphasis on thermochemical conversion. KTH Labs enable users to study fundamental biomass combustion and gasification physics via innovative fuel utilization approaches, including high-temperature fuel/oxidant preheating, catalytic combustion and gasification, and high-pressure gasification.

Facilities in KTH Labs were offered in FP6 SUSPOWER (2004-2009), encompassing 510 experimental-days with 26 user groups and 45 users, and in FP7 BRISK (2011-2015), encompassing 221 experimental-days with 12 user groups and 14 users. This represents a proven track record of enabling high-quality research for guest users. Several other international visitors are also hosted by these facilities.
