Characterization of Linked Polymer Solutions (LPS) – Influence of salinity and divalent ions
(Master thesis, 2011-05-31)Water flooding with addition of polymers cross-linked by polyvalent ions (LPS) has proven to increase the oil recovery both in field applications and laboratory studies, but with constraints on the brine salinity. With of ... -
Enzymes for Enhanced Oil Recovery (EOR)
(Doctoral thesis, 2011-06-30)Primary oil recovery by reservoir pressure depletion and secondary oil recovery by waterflooding usually result in poor displacement efficiency. As a consequence there is always some trapped oil remaining in oil reservoirs. ... -
Online monitoring of an organic synthesis reaction using Raman and NIR spectroscopy
(Master thesis, 2011)The synthesis of 10-Bromo-1-Decandiol was monitored using Raman and near infrared spectroscopy. Optical fiber Raman and near infrared probes were immersed in the reaction mixture. Raman spectra were recorded every 50 second ... -
Origin and character of gaseous hydrocarbons in the hydrate and non-hydrate charged sediments on the Norway - Svalbard margins
(Doctoral thesis, 2011-05-26)Gas incubated in clathrate water-structures, stabilizes the hydrogen bonded substance termed gas hydrate. In the marine environment vast amount of carbon is stored as gas hydrates within the temperature and pressure zone ... -
Synthesis of Some Nitrogen Heterocycles of Medicinal Relevance
(Doctoral thesis, 2012-04-18)In the first part of the project, two highly functionalized terminal alkynes, 3,3,4,4- tetraethoxybut-1-yne (TEB) and 1,1-diethoxy-but-3-yn-2-one (keto-TEB) have been used for the synthesis of 1,4-disubstituted 1,2,3-triazoles. ... -

Undersøking av katalysatorar ved solvolyse av lignin og analysering av produktet ved GC-MS, IR og NMR
(Master thesis, 2011-09-08)Med tanke på at petroleum er ein avgrensa ressurs og det moderne samfunnet er så avhengig av den, er det viktig å finne alternativ. Det er nødvendig med alternativ både til drivstoff og til kjemikalieproduksjon. Solvolyse ...
