Catalytic oxidation of NO to NO2 for nitric acid production over a Pt/Al2O3 catalyst
(Peer reviewed; Journal article, 2018)The oxidation of nitric oxide (NO) to nitrogen dioxide (NO2) is a key step both in NOx abatement technologies as well as in the Ostwald process for nitric acid production. A 1 wt.% Pt/Al2O3 catalyst was used to study ... -
Fast redox kinetics of a perovskite oxygen carrier measured using micro-fluidized bed thermogravimetric analysis
(Peer reviewed; Journal article, 2020)Redox kinetics of oxygen carrier in chemical looping combustion (CLC) is important for reactor design and its oxidation enthalpy is important in order to establish auto thermal demonstration. Most published redox kinetics ... -
Heterogeneous reaction kinetics of a perovskite oxygen carrier for chemical looping combustion coupled with oxygen uncoupling
(Peer reviewed; Journal article, 2020)The determination of more exact heterogeneous kinetics of oxygen carriers is a crucial task for modelling, used to predict performance and design of demonstrating pilot units. Thermogravimetric analysis (TGA) is the most ... -
Industry-scale production of a perovskite oxide as oxygen carrier material in chemical looping
(Peer reviewed; Journal article, 2021)How to upscale the production of oxygen carrier particles from laboratory level to industrial level is still challenging in the field of chemical looping. The upscaled oxygen carrier must maintain its physical and chemical ... -
Influence of substitution of water by organic solvents in amine solutions on absorption of CO2
(Peer reviewed; Journal article, 2018)Aqueous amine solutions are the most used solvents for chemical absorption of CO2. Substituting part of the water by organic solvents in aqueous amine solutions aims to take advantage of the lower partial pressure and ... -
Kinetic study of vacuum evaporation of elements from ternary melts; case of dilute solution of P in Si-Al melts
(Journal article; Peer reviewed, 2019)This research is devoted to study phosphorus removal from Si-Al alloys by vacuum refining of the ternary system of dilute solutions of P in Si-20 wt%Al. The experiments were carried out in an induction furnace and after ... -
Perovskite oxygen carrier with chemical memory under reversible chemical looping conditions with and without SO2 during reduction
(Peer reviewed; Journal article, 2021)Oxygen carrier materials (OCM) are usually exposed to sulfur-contained gases in the fuel reactor for chemical looping combustion. This work provides both experimental and model work to understand the SO2 effect on the ... -
Reduction and Dissolution Behaviour of Manganese Slag in the Ferromanganese Process
(Journal article; Peer reviewed, 2020)The reduction and liquidus behaviour of manganese slag with different basicities were studied in non-isothermal experiments in the temperature range of 1400–1500 °C. Certain amounts of quartz were added to Assmang ore ... -
Transformation Kinetics of Burnt Lime in Freshwater and Sea Water
(Peer reviewed; Journal article, 2020)Calcium oxide (CaO), also known as burnt lime, is being considered as a possible treatment to reduce the negative impact of sea urchins on tare forests in northern coastal waters and blue-green algal blooms in the surrounding ...
