Shadowing Effects of Monofunctional Catalysts in TAP Reactors
Industrial catalytic processes require tailored catalysts with an optimized performance to reduce energy consumption and waste products. Besides an optimum temperature, pressure, and composition, the distribution of active material can be seen as a valuable additional design variable. ... En savoir plus
Implications of Sorption on Carbon Dioxide Sequestration in Gas Shales
Gas shales are one of the potential sinks considered for carbon dioxide sequestration. Therefore further research on the importance of sorption on the carbon dioxide sequestration potential is highly topical. Experimentally measured maximum sorption capacity of carbon dioxide was about ... En savoir plus
Strong multiphysics coupling towards simulation of edible oil hydrogenation in monolith type reactor
Different phenomena control the performance and even selectivity in multiphase reactors. Moreover, a two way coupling between the physics could be expected when physical and/or chemical properties depend on the conversion rate. Hence, this presentation aims to show a methodology to model ... En savoir plus

Computational Fluid Dynamic (CFD) Modelling of Methanol Steam Reforming in Microreactors
Microreactors have been used for renewable fuel production due to benefits such as, enhanced mass transfer, improved heat transfer and larger surface-area-to-volume ratios. The steam reforming of methanol over a CuO/ZnO/Al2O3 based catalyst (BASF F3-01) is investigated using 2-D packed ... En savoir plus
2D fluid dynamics modeling of a pyrolysis microreactor
Accumulation of plastic solid waste is a large share of municipal solid waste (MSW). Thermochemical treatment processes are a vital component of a sustainable integrated MSW management since they reduce the volume of the waste significantly. In conjunction with our efforts to develop ... En savoir plus
