Fast Reactor Technology designed by Argonne National Laboratory. Argonne has pioneered the development of fast reactors, which will ultimately prove vital to extending the world's uranium and thorium energy supplies and to removing the radiotoxicity from used nuclear fuel In this study, we demonstrate a mesoscale triphasic (gas–liquid–liquid) reactor for fast, transition metal catalyzed gas–liquid reactions, which is capable of delivering kg per day productivity at the single channel level. More generally, our study addresses the limits of scale up of multiphase flow reactors beyond the micro- and ://

Abstract. A study of fast reactions in three nozzle reactors of the same geometry has been investigated. The nozzle reactors are x 10¯³ m³ x 10¯³ m³ and x 10¯³ m³ respectively, and flow visualizations have been studied by injecting a tracer into the inlet and at the walls of the :// A study of fast reactions in three nozzle reactors of the same geometry has been investigated.

Chemical kinetics and reactor design are at the heart of producing almost all industrial chemicals, such as the manufacture of phthalic anhydride shown in Figure 1 Ideal reactors and some real reactors that approximate the same flow pattern (Towler and Sinnott, ) Vapor-Liquid Reactors.
Vapor-liquid reactions are important in many chemical processes. For example, oxygenation and hydrogenation reactions are usually carried out with the organic component in the liquid phase (Towler and Sinnott, ).
Fig. 2 presents geometrical configurations of curved pipe reactors where chaotic advection is known to accelerate heat transfer, macro- and micromixing and the course of fast chemical reactions: meander (Habchi et al., ), lemniscate (Slominski et al., ), twisted bends (Castelain et al.,Acharya et al.,Boesinger et al., The present study is in two parts, the first part describes an investigation that was undertaken to determine the feasibility and hydrodynamic behaviour of a cold model circulating fluidized bed system proposed for the continuous combustion-gasification of biomass.
The design is based on the principle that the char produced in the gasifier is CFD study of nozzle reactor for fast HTL assuming non-Newtonian fluid.
In this study, a full geometry of nozzle reactor similar to that presented in Fig. B has been created. In the first instance, the thermodynamic and fluid dynamic setup was similar to that presented in the Newtonian simulation :// Magnox reactors (see Fig (a)) were built in the UK from to but have now been superseded.
The Magnox reactor is named after the magnesium alloy used to encase the fuel, which is natural uranium metal. Fuel elements consisting of fuel rods encased in Magnox cans are loaded into vertical channels in a core constructed of graphite Importance of Mixing in Fast Reactions Tips for Lab Operations.
In an example from the webinar, The Importance of Mixing, Ray Machado PhD, rm2 Technologies LLC and Air Products and Chemicals, optimizes mixing for fast reactions in an automated synthesis the reaction of S 2 O and I 2 in the presence of starch, he demonstrates the impact of mixing on the reagent distribution by The recent trend in this area is towards heterogenizing these reactions.
A mechanistic study of various uncatalyzed and catalyzed oxidations (cyclohexane, glycerol are two examples) are being undertaken to understand the catalyst-support interaction with various catalysts, and also the reaction-engineering aspects in industrial type :// Rapid, in situ, and label-free chemical analysis in microfluidic devices is highly desirable.
FT-IR spectroscopic imaging has previously been shown to be a powerful tool to visualize the distribution of different chemicals in flows in a microfluidic device at near video rate imaging speed without tracers or dyes. This paper demonstrates the possibility of using this imaging technology to study, the correlation from Liu and Macedo () was used to estimate the water diffusivity.

The electrochemical study of fast catalytic reactions is limited by mass transport when using the conventional electrochemical cell with a rotating disk electrode (RDE). To overcome this issue, it is important to find a new device with improved transport properties that Many desirable organic reactions are accompanied by side reactions and undesired by-products, which waste raw materials and complicate product work-up and isolation.
By enhancing the competition between reactions to obtain more selective syntheses, ecological and economic benefits may be expected. The most effective way to do this is usually ://Deposition of polysilicon (poly-Si) was tried to increase productivity of poly-Si by using two different types of gas nozzle in a monosilane Bell-jar Siemens (MS-Siemens) reactor.
