Kinetic study of dry reforming of Methane with Ni over different supports and Pt/Al2O3
… For each catalyst, a corresponding kinetic model needs to be established. These kinetic schemes should be sophisticated enough to describe the consumption rates, meanwhile rather simple for industrial applications. In this thesis, we intend to investigate three aspects. The first is to …

Development and Application of in Situ/Operando Spectroscopic Techniques for Understanding Active Sites and Surface Intermediate Species in Heterogeneous Catalysis
… and the formation of reactive oxygen species. A Langmuir-Hinshelwood model was proposed, integrating spectroscopic and kinetic data to describe surface reactions and charge transfer processes. This work demonstrates the power of integrated spectroscopic and kinetic methodologies for unraveling …

Iron-Doped Titanium Dioxide Nanomaterials: Synthesis, Characterization and Photodegradation Catalytic Behavior
… charge affects the dye adsorption. Using the Langmuir-Hinshelwood model, rate constants (kobs) decreasing with an increase in the molar percentage of iron in TiO2 as well as a decrease in the materials band gap. This trend is opposite to what was expected and it could be due to a significant …

Composites of Spherical Polyelectrolyte Brushes and Nanoparticles – Synthesis, Characterization and Their Use in Catalysis
… morin by hydrogen peroxide was established as a model reaction. It could be shown by UV/vis measurements that the rate of the decomposition is highly depending on the ratio between morin and the oxidant H2O2. This finding was modeled by a Langmuir-Hinshelwood reaction mechanism. The study proved …

Removing the Quantum Barrier to Sustainable LH2 Fuel in Aviation: A Mechanistic, Process, and Environmental Life Cycle Assessment of the Ortho-Para Conversion in Liquefaction
… a large-scale hydrogen liquefaction process was modelled using Aspen Plus. This study systematically compared perfect, imperfect, and post-liquefaction OPC strategies. Results demonstrate that achieving high-purity (99.6%) para-H2 for long-term storage can increase the Specific Energy Consumption …

Preparation, characterization and carrier gas transport characteristics of inorganic and organic membranes for application in lactic acid esterification with ethanol.
… described based on two simplified mechanisms of Langmuir Hinshelwood model to describe the adsorption components on the surface of the catalysts. The lactic acid feed gave a conversion rate of up to 100 % confirming the effectiveness of the acetate membrane impregnated resin catalysts in the …
