EUROKIN, a European cooperation initiative on reaction kinetics research 

Advisors: Prof.dr. F. Kapteijn, Prof.dr. J.A. Moulijn

Period: Since August 1998

Aim

The aim of the EUROKIN network is to produce a toolkit for estimating or measuring kinetic data and interpretation of those data by means of appropriate software routines. It will enable faster and lower cost derivation of kinetically based models, ultimately leading to more efficient commercial reactor design, quicker scale up and more efficient use of raw materials at lower costs. The active work in the Eurokin network will be continued in the coming years.

Consortium

The EUROKIN Consortium currently consists of 9 European companies (see logos) and 7 academic centres (TU Delft, Ghent University, UCL Louvain-la-Neuve, NTNU Trondheim, CNRS-IRCELyon, Politecnico di Milano, and TU München).

Test methods and reactors

General overviews and other means guide the user through the experimental part of the kinetic investigation:

  1. Selection of a suitable method and test reactor (also for high throughput);
  2. Spreadsheets to check for the absence of transport limitations and other pheno­mena causing non-ideality for various reactor types: (i) fixed beds, (ii) trickle beds, (iii) slurry and other agitated reactors, (iv) Robinson-Mahoney reactors, and (v) catalytic-wall reactors for fast reactions.

Additionally, we focus on kinetic studies in difficult situations: (i) presence of irreducible transport limitations (special experimental techniques and software); (ii) catalyst deactivation and regeneration, (iii) dynamically operated reactors.

Reaction kinetics software

EUROKIN also helps the user to with methods and software required for modeling the kinetics in reactors. The following items are addressed:

  1. Ab-initio methods;
  2. Complex reaction networks and lumping;
  3. Liquid-phase kinetics;
  4. Computational fluid dynamics (CFD);
  5. Dynamic methods
  6. Reactor modelling for the 'difficult situations' as described above;
  7. Kinetic parameters estimation;
  8. Design of experiments;
  9. Extraction of kinetics from large data sets;
  10. User-friendliness.


Finally, EUROKIN pays attention to the implementation of kinetics (including un­certain­ties) in plant performance simulations.
