Activity and segregation behavior of Pd75%Ag25%(1 1 1) during CO oxidation – An in situ NAP-XPS investigation
(Journal article; Peer reviewed, 2022)The surface reactivity during CO oxidation over Pd(1 1 1) and Pd75%Ag25%(1 1 1) single crystals has been investigated using near ambient pressure X-ray photoelectron spectroscopy (NAP-XPS) under excess oxygen conditions ... -
Effects of Ni-Co Ratio on Deactivation and Coke Formation in Steam Reforming of Hydrocarbon Impurities from Biomass Gasification with Ni-Co/Mg(Al)O Catalysts
(Peer reviewed; Journal article, 2022)Ni-Co/Mg(Al)O catalysts with different Ni-Co ratios (40-0, 30-10, 20-20, 10-30 and 0-40 wt%) have been tested for steam reforming of hydrocarbon impurities in a model biomass gasification syngas at relevant operating ... -
Experimental and Theoretical Studies on Water-Added Thermal Processing of Model Biosyngas for Improving Hydrogen Production and Restraining Soot Formation
(Journal article; Peer reviewed, 2022)The upgrading of biosyngas to convert methane into syngas is a necessary step for hydrogen production from biomass. However, this process is highly energy-demanding. In this study, a model biosyngas containing H2, CH4, CO, ... -
Fischer-Tropsch synthesis—Investigation of the deactivation of a Co catalyst by exposure to aerosol particles of potassium salt
(Journal article; Peer reviewed, 2018)The influence of potassium species on a Co based Fischer-Tropsch catalyst was investigated using an aerosol deposition technique. This way of poisoning the catalyst was chosen to simulate the actual potassium behaviour ... -
Mn promoted Co catalysts for Fischer-Tropsch production of light olefins – An experimental and theoretical study
(Journal article; Peer reviewed, 2018)Three different CoMn/gamma-Al2O3 catalysts were prepared by the incipient wetness impregnation route and compared to a Co/gamma-Al2O3 catalyst. The effect of co-impregnation vs. sequential impregnation as well as the order ... -
The O-factor: using the H-factor concept to predict the outcome of organosolv pretreatment
(Peer reviewed; Journal article, 2021)The H-factor, a parameter used extensively to analyze and predict the outcome of kraft pulping, is applied to organosolv pretreatment. The total solid yield after organosolv pretreatment fits well with the H-factor. The ... -
Steam Reforming of Tar Impurities from Biomass Gasification with Ni-Co/Mg(Al)O Catalysts—Operating Parameter Effects
(Peer reviewed; Journal article, 2024)The elimination of tar impurities from biomass gasification by catalytic steam reforming can provide clean syngas for downstream biofuel synthesis (Fischer–Tropsch). The effects of key operating parameters in CH4/tar steam ... -
Transition-Metal Nanoparticle Catalysts Anchored on Carbon Supports via Short-Chain Alginate Linkers
(Journal article; Peer reviewed, 2021)This study reports a green, inexpensive, and highly versatile procedure to synthesize well-dispersed transition-metal nanoparticles anchored on carbon supports. The resulting metal loadings are 26 wt % or above. Achieving ... -
Understanding Carbamate Formation Reaction Thermochemistry of Amino Acids as Solvents for Postcombustion CO2 Capture
(Journal article; Peer reviewed, 2019)The carbamate stability constant for a data set of 10 amino acids, having potential for being postcombustion CO2 capture (PCC) solvents, has been calculated using various implicit and explicit solvation shell models. This ... -
Vapour-liquid equilibria in pure N-Methyl-1,3-diaminopropane (MAPA), 1,3-diaminopropane (DAP), 2-(Isopropylamino)ethanol (IPAE), N-tert-Butyldiethanolamine (N-TBDEA) and their aqueous solutions
(Journal article; Peer reviewed, 2020)New energy effective solvents are in demand to make global CO2 capture feasible. Phase change solvents seem to be one avenue to reach this goal. This paper presents new experimental data and modelling results for four ...
