(Master thesis, 2023)Som en av de mest betydningsfulle primærprodusentene i havet, frigjør tang og tare betydelige mengder organisk karbon under vekst og nedbrytning. Likevel er det lite kunnskap om forholdet mellom de biologiske og kjemiske ... -
Production and nutritional adaptation of the brine shrimpArtemia sp. as live food organism for larvae of marine cold water fish species
(Doctoral thesis, 2001)High nutritional value of Artemia sp. refers to high content of highly unsaturated fatty acids (n-3 HUFA) and in particular the content of DHA. In the enrichment experiments presented in this thesis new diets and one new ... -
Production of 2nd generation dolomite-based solid sorbents for high-temperature CO2 capture
(Master thesis, 2022)Verden står overfor en stadig økende miljøtrussel forårsaket av økende utslipp av menneskeskapt karbondioksid, det er derfor avgjørende å finne strategier for å redusere disse utslippene. Calcium-looping (Ca-L) har dukket ... -
Production of fuel-cell grade H2 by sorption enhanced steam reforming of acetic acid as a model compound of biomass-derived bio-oil
(Journal article; Peer reviewed, 2016)Fuel-cell grade H2 has been produced by the sorption enhanced steam reforming (SESR) of acetic acid, a model compound of the bio-oil obtained from the fast pyrolysis of biomass. A Pd/Ni–Co catalyst derived from a ... -
Production of high pressure pure H2 by pressure swing sorption enhanced steam reforming (PS-SESR) of byproducts in biorefinery
(Peer reviewed; Journal article, 2018)Hydrogen is highly demanded in biorefinery, and hydrogen production from renewable sources is essential to produce truly green transportation fuels from biomass. The present work demonstrates experimentally the production ... -
Production of Iron Alloy by Direct Electrolytic Reduction Using Suspension Electrolysis in an Alkaline Electrolyte
(Peer reviewed; Journal article, 2022)Iron alloys were produced by suspension electrolysis in a 50 wt% NaOH–H2O electrolyte at 383 K, and Fe–Cr and Fe–Ni alloys were obtained using a suspension of Fe2O3+Cr2O3 and Fe2O3+Ni(OH)2 particles, respectively. Highly ... -
