Optimization of a Reactor Network for Production of Butyl Butyrate by an Attainable Region Analysis
Krog, Halvor Aarnes (Master thesis, 2017)Butyl butyrate is a promising supplement for jet fuel and diesel. It can be produced in a biotechnological process, by an esterification reaction between butanol and butyric acid. These intermediates can in turn be produced ... -
Residence time distribtion: Konduktivitetsmålinger på eksperimentell tubulær blandetank reaktor
Munkebye, Knut-Arne Rademacher (Master thesis, 2012)Denne oppgaven har gått ut på å bygge en forsøksrigg til bruk på felleslab, ved Institutt for kjemisk prosessteknologi ved NTNU. Det skulle kjøres forsøk på oppholdstidsdistribusjoner/Residence time distributions. Alt av ... -
Response Surface Methodology for Understanding Glucose and Xylose Utilization by Clostridium beijerinckii NCIMB 8052
Birgen, Cansu; Markussen, Sidsel; Wentzel, Alexander; Preisig, Heinz A. (Peer reviewed; Journal article, 2018)We applied response surface methodology to understand the effect and extend of carbon catabolite repression (CCR) on growth of Clostridium beijerinckii NCIMB 8052 using xylose and glucose as representative lignocellulosic ... -
A Simplification Procedure for Distillation Tray Models
Edvardsen, Johan Christian (Master thesis, 2018)The popularity of liquid separation by distillation in the industry has resulted in a wide range of distillation models. These models range from detailed flow models used in the design of trays and packings, to models ... -
Spline Type Modulating Functions for Preprocessing of Raman Spectra for Quantitative Analysis
Rasmussen, Julie Kristine Bonnevie (Master thesis, 2019)Raman-spektroskopi gir informasjon om molekylære vibrasjoner som kan brukes til å identifisere og kvantifisere bestanddelene av ulike materialer. Metoden er imidlertid svært følsom ovenfor kraftig støy. En konsekvens av ... -
Studies on delignification and inhibitory enzyme kinetics of alkaline peroxide pre-treated pine and deodar saw dust
Baksi, Sibashish; Sarkar, Ujjaini; Saha, Sudeshna; Ball, Akash K.; Kuniyal, Jagdish Chandra; Wentzel, Alexander; Birgen, Cansu; Preisig, Heinz A.; Wittgens, Bernd; Markussen, Sidsel (Peer reviewed; Journal article, 2019)Delignification of lignocellulosic biomass by alkaline peroxide pre-treatment is a preliminary important step for an overall biomass fractionation process. In the present work, saw dusts are pre-treated by aqueous alkaline ... -

Topology-based construction of business-integrated material modelling workflows
Preisig, Heinz A.; Klein, Peter; Konchakova, Natalia; Hagelien, Thomas Fjæstad; Friis, Jesper; Horsch, Martin Thomas (Chapter, 2022)Designing a new product requires information from the business and physical domains, which implies integrating business decision tools with process and material simulation processes to form an overall workflow. The integration ... -
Valorization of lignocellulosic waste (Crotalaria juncea ) using alkaline peroxide pretreatment under different process conditions: An optimization study on separation of lignin, cellulose, and hemicellulose
Baksi, Sibashish; Saha, Sudeshna; Birgen, Cansu; Sarkar, Ujjaini; Preisig, Heinz A.; Markussen, Sidsel; Wittgens, Bernd; Wentzel, Alexander (Peer reviewed; Journal article, 2018)Lignocellulose materials, essentially consisting of lignin, cellulose and hemicelluloses, are abundant sources of fermentable sugars. The bast fiber of Crotalaria juncea (Sunn hemp), a native cover crop of India, was used ...
