(Peer reviewed; Journal article, 2022)A detailed but still central processing unit (CPU)-efficient bed model for grate-fired combustion of biomass and waste is developed. Simulations of wood chip combustion are performed, and the results are compared to ... -
Carbon Capture Utilization and Storage in Methanol Production Using a Dry Reforming-Based Chemical Looping Technology
(Peer reviewed; Journal article, 2022)This further investigates the concept of gas switching dry reforming (GSDR) that efficiently converts the two major greenhouse gases (CO2 and CH4) into a valuable product (syngas) for gas-to-liquid (GTL) syntheses. The ... -
Carbonization of biomass in constant-volume reactors
(Journal article; Peer reviewed, 2017)A novel carbonization process that realizes near-theoretical fixed-carbon yields in ∼3 h is presented. Norwegian spruce and birch sawdusts were carbonized in a hermetically sealed reactor at an initial nitrogen pressure ... -
Charcoal "Mines" in the Norwegian Woods
(Journal article; Peer reviewed, 2016)This paper presents lab-scale flash carbonization (FC) experiments under elevated pressure using Norwegian wood as a feedstock. The silicon and ferrosilicon industry of Norway has been urged to reduce fossil CO2emissions ... -
