Process parameters affecting the sustainability of fermentative hydrogen production: A short review
(Journal article; Peer reviewed, 2011)Anaerobic fermentation is regarded as the least energy intensive method for H2 production. Extensive literature on experimental attempts to achieve the highest possible theoretical yield (e.g. 4 mol H2/mol glucose) is ... -
Simulation of Simplified Model for Reaction Kinetics in Biomass Gasification
(Conference object; Peer reviewed, 2015-11-25)Due to complexity in interactions between solid particles and between particles and carrier fluid, modeling of biomass gasification kinetics has been shown to be very challenging. Some commercial packages such as Barracuda ... -
Simultaneous hydrogen production and consumption in Anaerobic mixed culture fermentation
(Journal article, 2012)The aim of the present study is to investigate the relevance of homoacetogenic H2 consumption on the bio-hydrogen yield and products distribution in mixed culture fermentation. A hybrid anaerobic reactor was operated for ... -
Statistical diagnosis of a gas-solid fluidized bed using Electrical Capacitance Tomography
(Journal article; Peer reviewed, 2012)Fluidization experiments were performed using several particle size distributions of spherical glass particles, ranging from Geldart B to D. An Electrical Capacitance Tomography (ECT) tomograph was utilised in the present ... -
The impact of staged combustion on the operation of a precalciner cement kiln
(Doctoral theses at NTNU;1999:89, Doctoral thesis; Peer reviewed, 1999)In this thesis, the impact of staged combustion on the operation of a precalciner cement kiln, is considered. Mathematical modelling and full-scale experiments at the Norcem cement works in Brevik, Norway, is the basis for ... -
The influence of the experimental span of Time-resolved X-ray tomography on dynamic parameters in a fluidized bed
(Journal article; Peer reviewed, 2011)Fluidized beds have presented some problems to experimentalists in the past due to their opaque nature [1]. This problem has however been overcome by non-intrusive nor invasive measurement techniques. X-rays or Gamma rays ... -
Velocity and turbulence measurements of oil-water flow in horizontal and slightly inclined pipes using PIV
(Chapter; Peer reviewed, 2009)Oil-water flows in horizontal and slightly inclined pipes are investigated using Particle Image Velocimetry (PIV). PIV offers a powerful non-invasive tool to study such flow fields. The experiments are conducted in a 15 m ...
