The fixed beds have the advantage of large heat transfer area, for they are used in some designs of innovative nuclear reactors as the reactor FBNR. Inside of study of fixed beds is important to define the following parameters: flow minimum and velocity profile of cooling fluid, ... En savoir plus
The Life+ GreenWoolF project is aimed at demonstrating that green hydrolysis with superheated water is an effective way to convert wool wastes into organic nitrogen fertilizers. The core of the process is represented by the reaction tank (Figure 1) in which the hydrolyses reaction takes ... En savoir plus
The rise in atmospheric CO2 needs the development of efficient conversion technologies. CO2 reduction reaction (CO2RR) emerges as a compelling solution, offering the transformation of CO2 into more energetic compounds, such as fuels (hydrocarbons, alcohols, etc.) and valuable chemicals, ...

Recently, hydrogen is widely used as environmental energy and high energy content. The hydrogen is mainly produced by water gas shift reaction(WGSR) from coal to hydrogen process in Integrated Gasification Combined Cycle(IGCC) plant. WGSR, well known for hydrogen production, is a ... En savoir plus
Various hydrocarbon compounds have been converted into pure hydrogen by using a catalyst and a palladium membrane in one reactor (PMR) in a one-step process where the reaction proceeds to almost complete conversion. Octane is converted into pure hydrogen using of a palladium membrane ... En savoir plus
A novel type of photocatalytic reactor, i.e. parallel flow tube reactor (PFTR) is presented for the degradation of indoor air pollution with UV-light. A Multiphysics model was developed in COMSOL Multiphysics® to predict the steady-state behavior under different inlet concentrations and ... En savoir plus
In the field of chemical reaction engineering chemical kinetics and fluid dynamics are described by various mathematical approaches. Such tools help to shorten the time-to-market of novel products and processes. Thanks to the continuously improving computation power, it is possible to ... En savoir plus
A model was developed to simulate the reaction, concentration field, flow field, and temperature distribution inside a Claus reactor for converting hydrogen sulfide to sulfur. The model considered two ideal reactors, a continuous stirred tank reactor and a plug flow reactor. As expected, ... En savoir plus
Liquid Metal Fast Breeder Reactor (LMFBR) employs molten sodium as coolant due to its suitable neutronic and thermal properties. Measurement of coolant flow rate is a very important factor both from operational and safety aspects of a fast reactor. Good electrical conductivity of liquid ... En savoir plus
This paper presents a simulation approach to develop a model for understanding the mixing phenomenon in a stirred vessel. The mixing in the vessel is important for effective chemical reaction, heat transfer, mass transfer and phase homogeneity. In some cases, it is very difficult to ... En savoir plus
