Advanced reactor concepts for low cost CO2 capture

The Flow Technology group at SINTEF Industry has developed a unique infrastructure for testing, demonstration and scale up of advanced reactor concepts for decarbonization of the industrial and energy sectors. The investigated technologies cover adsorption-based CO2 capture, chemical looping for power and hydrogen production with integrated CO2 capture, and pyrolysis for combined hydrogen and carbon production.

The experimental activities have very strong links to reactor modelling and techno-economic assessments, which are used to demonstrate that competitive CO2 avoidance costs can be achieved with these technologies. The infrastructure is also highly flexible for running a wide variety of multiphase reactive systems under extreme conditions for testing and validation of novel systems and processes, as well as for model validation. 

Summary of infrastructure:

  • A single high temperature dense bed reactor (~1 kg powder load, 1 kWth, 10 bar & 1000 °C) with flexible gas feed system 
  • A three-reactor cluster for high temperature pressurized dense bed reactions (~40 kg powder load, 50 kWth, 20 bar & 1100 °C)
  • A high temperature pressurized Internal Circulating Reactor (4 kg powder load, 10 kWth, 10 bar & 1000 °C)
  • A reactor with inbuilt heat transfer surfaces for combined Vacuum Temperature Swing with heat integration currently used for adsorption post combustion CO2 capture (~20 kg powder load, 10 kWth, 0.05-1 bar pressure and up to 200 °C)
  • A small-scale reactor for breakthrough measurement under combined vacuum and temperature swings (~100 g powder load, 0.05 to 1 bar pressure and up to 200 °C)
  • Cold flow setups for proof of concept, flow visualization and measurement: 
    • A pseudo-2D membrane assisted fluidized bed (3-5 kg powder load)
    • A pseudo-2D internal circulating reactor (3-5 kg powder load
