Application of a Pseudo-Kinetic Generalized Serverity Model to the Concentrated Sulfuric Acid Hydrolysis of Pinewood and Aspenwood
Janga, Kando Khalifa; Øyaas, Karin; Hertzberg, Terje; Moe, Størker (Journal article; Peer reviewed, 2012)The yield of monosaccharides after two-stage concentrated sulfuric acid hydrolysis of softwood (Scots pine) and hardwood (trembling aspen) was modeled using a generalized severity parameter with a time-independent rate ... -
Hybrid Life Cycle Assessment of Wood-based Biofuel Production and Consumption Scenarios in Norway
Bright, Ryan (Master thesis, 2008)An increasingly urgent need to develop alternatives to fossil fuels in road trans- portation stems from both the need to combat climate change and the need to prepare for a transition beyond peak oil. Biofuels can be part ... -
Single-step microwave-assisted hot water extraction of hemicelluloses from selected lignocellulosic materials – A biorefinery approach
Mihiretu, Gezahegn T.; Brodin, Malin; Chimphango, Annie F.; Øyaas, Karin; Hoff, Bård Helge; Görgens, Johann F. (Journal article, 2017)The viability of single-step microwave-induced pressurized hot water conditions for co-production of xylan-based biopolymers and bioethanol from aspenwood sawdust and sugarcane trash was investigated. Extraction of ...
