Green River Kerogen Product Distribution Analysis: The Influence of Pyrolysis and Catalytic Reactions with Hydrogen-Donor Solvent
(Master thesis, 2016)The increase in global energy consumption of petroleum, which is estimated to even surge to ca. 37% by 2035, requires substitutes from other unconventional sources of oil and gas. Utilization of oil shale by technology and ... -
Growth and Aggregation Phenomena in Precipitation of Calcium Carbonate
(Dr. ingeniøravhandling, 0809-103X; 2001:49, Doctoral thesis, 2001)Particle size-enlargement processes in precipitation of calcium carbonate have been investigated by focusing on determination of crystal growth rates and aggregation rates of the metastable polymorph vaterite. This was ... -
H-2-selective Troger's base polymer based mixed matrix membranes enhanced by 2D MOFs
(Peer reviewed; Journal article, 2020)In this work, two two-dimensional (2D) leaf ZIFs (ZIF-L-Zn and ZIF-L-Co) were incorporated into the Troger's base (TB)-based polymers for hydrogen separation. SEM imaging and enhanced performance have demonstrated good ... -
H2 production by sorption enhanced steam reforming of biomass-derived bio-oil in a fluidized bed reactor: An assessment of the effect of operation variables using response surface methodology
(Journal article; Peer reviewed, 2014)High-purity H2 was produced by the sorption enhanced steam reforming (SESR) of acetic acid, a model compound of bio-oil obtained from the fast pyrolysis of biomass, in a fluidized bed reactor. A Pd/Ni–Co hydrotalcite-like ... -
HAMLET forms annular oligomers when deposited with phoshpolipid monolayers
(Journal article; Peer reviewed, 2012)Recently, the anticancer activity of human α-lactalbumin made lethal to tumor cells (HAMLET) has been linked to its increased membrane affinity in vitro, at neutral pH, and ability to cause leakage relative to the inactive ... -
