Fischer-Tropsch synthesis – Influence of aerosol – deposited potassium salts on activity and selectivity of Co based catalysts
(Doctoral theses at NTNU;2018:104, Doctoral thesis, 2018)The effect of potassium salts (K2SO4, KNO3, KCl, K2CO3) on cobalt based Fischer-Tropsch catalysts has been studied experimentally and theoretically. In order to better understand the deactivation effect of potassium species, ... -
Naphthenic acid solubility in produced water and their interactions with divalent cations
(Doctoral theses at NTNU;2018:259, Doctoral thesis, 2018)To keep up with the growing energy demands, the production of high acid crudes is increasing worldwide. This acidity is mainly caused by a subgroup of resins called naphthenic acids. With the increased production and ... -
Optimal Operation of Integrated Chemical Processes: With Application to the Ammonia Synthesis
(Doctoral theses at NTNU;2018:222, Doctoral thesis, 2018)Chemical processes have to be operated at their economic optimum to remain competitive. This is called optimal operation. Optimal operation is frequently incorporated using a real-time optimization approach. In this approach, ... -
Simple and Robust Formulations of the Unscented Kalman Filter and Model Predictive Control
(Doctoral theses at NTNU;2024:93, Doctoral thesis, 2024)This thesis focuses mainly on state estimation by the Unscented Kalman filter (UKF), and partly on robust nonlinear model predictive control (RNMPC). Our aim is to refine or develop algorithms which are simple to implement, ...
