Integrating exothermic and endothermic reactions within a single reactor offers a promising strategy to enhance overall thermal efficiency. However, existing systems often suffer from limited heat transfer performance due to design and heat transfer constraints. To overcome this ... Per saperne di più
In this presentation we are dealing with the computational fluid model of a Filament Assisted Chemical Vapor Deposition (FACVD) reactor. Proposed strategy in this study involved several steps: (a) development a computational model for FACVD process capable to describe and obtain with ... Per saperne di più
Most reactor designs are based on pseudo homogeneous models. This paper studies the COMSOL simulation of a packed bed reactor using a 2-D heterogeneous model. The case considered was a packed reactor with spherical catalyst for oxidation of o-xylene in air to phthalic anhydride. Large ... Per saperne di più
The yield and selectivity of a chemical reactor are controlled by the rates of desired reactions relative to those of undesired side reactions. These reaction rates are controlled by the local concentration of reactants, as often described by elementary rate laws. Chemical engineers ... Per saperne di più
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 ... Per saperne di più
Metal-organic chemical vapour deposition (MOCVD) is a well-known process to produce high quality thin films that can protect, ennoble and functionalize metallic tools. To realize a high performance coating on a complex 3D mold surface, knowledge about the material formation from a ... Per saperne di più
The reversible storage of hydrogen in metal hydrides represents an attractive technology for hydrogen-based energy systems. In addition to their application as pure hydrogen storage media, metal hydrides can also be used to develop thermochemical hydrogen compressors, which can be ... Per saperne di più
Induction heating (IH) [1] is a good candidate for decarbonization of chemical processes: energy savings, process intensification and production costs reduction [2-5]. Heat can be generated directly into the reactor at the surface in contact with the gas flux passing through a specific ... Per saperne di più
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 ... Per saperne di più
Many industrial applications require special treatments for fluid products, such as: deagglomeration, dispersion, homogenization, emulsion, special mixing or even catalysis of chemical reactions. Such effects can be obtained through cavitation in a closed ultrasonic reactor, in which it ... Per saperne di più
