In this work, the modeling of an industrial scale, single tube, packed bed reactor for steam reforming (SR) application, typically used to provide hydrogen for ammonia synthesis, is discussed. The tightly coupled mass, energy, and momentum equations used to describe the system have been ... En savoir plus

The versatility of the 3D printing technology has allowed developing originally structured catalysts for interesting reactions, for instance, the 0.5wt.%Fe/SiC monoliths for the treatment of industrial wastewater. These monolithic structures, manufactured by Robocasting, have ... En savoir plus

Three-dimensional (3D) printed 0.52 wt.% Fe/SiC monoliths with interconnected channels, fabricated by direct ink printing or Robocasting, are feasible and robust catalysts for the hydroxylation of phenol to dihydroxybenzenes using hydrogen peroxide as oxidant in aqueous media [1]. ...

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

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

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

Introduction Over the last years, there has been an increasing interest in plastic recycling as an alternative to reduce fossil fuel dependency. In this light, chemical recycling has been presented as a promising strategy to maximise the recycling rate, although this technology presents ... En savoir plus

The progress within the field of additive manufacturing has eased the fabrication of new reactor geometries significantly. It is possible to design and print a reactor of tailored shape and size at comparatively low costs and short time. Printing and testing all sensible reactor designs ... En savoir plus

The time-dependent operation of methanol, ammonia, and urea production units embedded in a steel mill technical environment is analyzed with dynamic simulation models. From different process concepts and gas availability scenarios a set of simulation cases is defined with blast furnace ... En savoir plus

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
