In the early 1920’s, Gas-To-Liquids (GTL) and Coal-To-Liquids (CTL) technologies were developed to account for the depleting crude oil resources [1]. During this period, Franz Fischer and Hans Tropsch developed a process to convert synthesis gas (syn gas), derived from coal ... Per saperne di più
For design of radial flow fixed bed reactors, it is important to ensure proper flow distribution through the catalyst bed. A 2D axisymmetric model of a radial-flow reactor was used to evaluate flow maldistribution through the catalyst bed and the pressure drop through the reactor for a ... Per saperne di più
The self-ignition of tetrafluoroethylene (TFE) caused by contact with hot surfaces has been analyzed with the help of simulations performed with COMSOL Multiphysics®. The current study focuses on large-scale heated reactors for the industrial production of polytetrafluoroethylene (PTFE) ... Per saperne di più
Many industrial, especially heterogeneously catalysed, processes are characterised by a strong interaction between the reaction kinetics and transport phenomena. Because experiments in laboratory scale can be very time- and cost-intensive, Temkin and Kul’kova developed a new reactor ... Per saperne di più
Nowadays mathematical models are applied in almost every field of our life to predict how real systems behave. Computational Fluid Dynamics (CFD) has become a standard tool for analyzing various situations where fluid flow has a significant effect on the studied processes. Complex models ...

ICP reactors are usually meter sized and driven at RF frequencies, for example at 13.56 MHz. We developed a miniature resonator allowing an inductive type of coupling of microwaves at 2.45 GHz to a plasma jet, flowing in ceramic tubes. Previous experiments and simulations show an ...

One challenge with converting nuclear research reactors to low enrichment fuels is the thermal-fluid performance. Local areas of high temperature, known as hotspots, limit reactor performance and thus require accurate modeling. A simplified fuel plate model is eveloped to compare ... Per saperne di più
Gallium nitride (GaN) and its related nitride alloys with special physical properties are in technical areas of high interest. The growing of gallium nitride boules on non-native sapphire or silicon carbide requires complicated mechanisms of defect reduction in the lattice structure. ... Per saperne di più
The current general context for green production and decarbonation prompts considering alternative solutions to produce high added value byproducts from gas decomposition without producing CO2. Steam Reforming or Combustion processes, widely applied in Industry, need H2O or O2 to ... Per saperne di più
The findings presented in this report are results of a five-year effort led by the Research Reactors Division (RRD) of the Oak Ridge National Laboratory (ORNL), which is focused on research and development toward the conversion of the High Flux Isotope Reactor (HFIR) fuel from high ...
