(Mixed) Oxide Synthesis by Automated pH-Controlled Precipitation, Ion Exchange and Sol-Gel Process (reaction preparation, synthesis, washing, drying)


MULTIPLANT / AUTOPLANT PRECIP

Robustness and ease-of-use by design

The leading technology in overhead gravimetric dispensing / dosing (patented) combined with our reactor and process excellence, and our user-friendly software, allow you to accelerate, standardize and digitalize your (mixed) oxide synthesis workflows (precipitation, sol-gel, ion exchange).

Key advantages

  • Decrease in cost per experiment up to 90+ %.
  • Increase in productivity by a factor of 10+.
  • Up to 36 experiments per run on an AUTOPLANT, up to 6 experiments per
    run on a MULTIPLANT.
  • Independent control of all process parameters in each reactor with PAT like
    PSD, pH.
  • Independent and precise temperature and stirring control in each reactor.
  • Up to 8 independent liquid feeds per reactor.
  • pH measurement and control (e.g. swingin pH control via acid and base).
  • Vessel-to-vessel transfer for multistep processes.
  • Gravimetric solid and viscous liquid dispensing.
  • 4-Needle Head for volumetric liquid handling and sampling.
  • Feeding and sampling under reaction conditions.
  • Cleaning in place (e.g. automated cleaning, inserts).
  • Dispensed amount, stirrer speed, temperature, pressure, time..., and other
    data are stored in a read only log file.
  • Easy access to data with a convenient interface to pull results into Excel or
    virtually any other software.
  • Interface to DOE.

Technical details

Chemspeed’s MULTIPLANT / AUTOPLANT deck modularity allows the user to execute and perform a variety of workflows in a fully or semi-automated fashion.

New or better, high-quality (mixed) oxides require accurate control of many reaction parameters, therefore automated workflow solutions are key to accelerate their development.

Reaction preparation

  • Interface to DOE. Gravimetric overhead dispensing of solids powders, and extrudates directly into the reactor.
  • Metal salt solution preparation.
  • Addition of liquid reagents and solutions.

Synthesis

  • Precise liquid and slurry feed with pH-control (acid, base).
  • Excellent mixing for slurries with e.g. 50+ % solid content.
  • Versatile stirring and temperature profiles.
  • Accurate and defined heating programs (+/- 0.1 °C)
    • Standard range: from -20 to 250 °C
    • (Optional extension to -50 °C or 350 °C).
  • Pressure up to 100 bar for e.g. precipitations under super-heated conditions.
  • Vessel-to-vessel transfer for multistep processes.
  • Online data visualization.
  • Logging of all reaction parameters.

Work-up

  • Filtration, washing.
  • Centrifugation.
  • Drying.

Post reaction treatment

  • Calcination and desiccation.
  • Compaction, crushing, sieving.

Analytics

  • Powder diffractometer.
  • Electron microscopy.
  • Parallel BET.
  • DSC and TGA.
  • Mercury porosimetry.

The cutting edge Process Development Workstation Technology allows scientists to truly mimic
the final industrial production process and provides all the flexibility to optimize integrated reaction sequences, even if a complex configuration of reactors and feed vessels required.
