Kinetic study of dry reforming of Methane with Ni over different supports and Pt/Al2O3
… a kinetic study on Ni series catalysts for dry reforming of methane (DRM) and comparison with a commercially noble metal catalyst Pt/Al2O3. For each catalyst, a corresponding kinetic model needs to be established. These kinetic schemes should be sophisticated enough to describe the …

DEVELOPMENT OF NOVEL CATALYSTS AND PROCESSES FOR SUSTAINABLE HYDROGEN TECHNOLOGIES
… propane dehydrogenation (PDH), CO₂ methanation, dry reforming of methane (DRM), and COₓ-free catalytic methane decomposition (CDM). A core challenge in these processes is catalyst sintering, which reduces stability and performance. The research develops anti-sintering strategies using single-atom …

ADVANCED BIFUNCTIONAL CORE-SHELL CATALYSTS FOR METHANE REFORMING USING CARBON DIOXIDE
Utilization of CO2 and CH4 to produce hydrogen or syngas via dry reforming of methane (DRM) reaction is an environmentally and commercially attractive prospect in view of the escalating global concerns on climate change from anthropogenic CO2 emissions. However, operational challenges stemming from …

The suitability of Ni-Co catalysts in the dry reforming reaction
In recent times, the dry reforming of methane has received significant interest as an alternative process through which synthesis gas can be produced. This is because dry reforming combines methane and carbon dioxide which are both greenhouse gases into synthesis gas which is used in the production …
