Catalysts synthesis

The REALCAT platform comprises two fully automated, flexible, modular robotic workstations from Chemspeed: Catimpreg and Autoplant.

Catimpreg - Chemspeed

Catimpreg is mainly designed to run automatically parallel syntheses of catalysts by coprecipitation and impregnation. It possesses an XYZ arm with a rotating alpha-axis and automatic tool exchange to perform automatically the following synthesis steps :

  • Gravimetric solid dispensing (from mg to g) of a wide range of solid (powder, extrudates,...).
  • Volumetric liquid dispensing (1 mPa.s - 200 mPa.s) and viscous liquid dispensing (>500 mPa.s).
  • pH and density measurement and adjustment.
  • Heating, reflux, vacuum, filtration...
  • Efficient mixing by orbital shaking while preserving the extrudates.

Inert atmosphere for sensitive reagents or inert reaction conditions can be assured in the Catimpreg workstation either by inertization of the reactors (vacuum-inert gas cycles) or by inertization of the entire workstations enclosed hood.

At ambient pressure, liquid phase catalyst testing is possible using the Chemspeed Catimpreg workstation, equipped with 36 reactors. This robot allows catalytic performance tests by parallel or successive reactions...


Autoplant - Chemspeed

Autoplant is mainly designed to automate parallel hydrothermal synthesis of catalyst and polymerization reactions. As Catimpreg workstation, it is possessing an X, Y and Z arm with rotating alpha-axis and automatic tool exchange to perform automatically the following synthesis steps: reagent preparation, solids and liquids dosing, filtration, extraction, evaporation, vortexing and reflux.

Eight fully automated and instrumented high pressure reactors (100 mL) are installed in the workstation. Each reactor is equipped with high pressure pump, gas flow and pressure controller. Injection of liquid and/or gas reagent, pressure (up to 80 bar) and temperature (-10°C to +250°C) in each reactor can be controlled individually. The reactor heads include an integrated reflux condenser and houses connectors for temperature and pH probes and liquid sampling. In addition, each reactor includes one feed vessel that is intended for the storage of reagents added to the reactor via the syringe pump in the course of an application. Different stirrer designs (anchor or twisted blade) can be used and are easily exchanged according to the reagent nature (gas, liquid or solid). Indirect online viscosity measurements can be carried out.

As in Catimpreg inert atmosphere for sensitive reagents or inert reaction conditions can be assured in the Autoplant workstation either by inertization of the reactors (vacuum inert gas cycles) or by inertization of the entire workstations enclosed hood. Moreover, hood is equipped with 4 gloves for some manually tasks under inert atmosphere. It is also equipped with H2O and O2 detectors permitting to control the atmosphere inside the workstation.

This robotic platform allows testing in parallel of 8 catalysts for a variety of solution phase homogeneous and heterogeneous catalyzed reactions. It also provides all the flexibility to optimize integrated reaction sequences.

Catalysts testing

Flowrence - Aventium

REALCAT platform is equipped with three compact stand-alone fixed bed reactor Flowrence systems (Avantium) designed to screen heterogeneous catalyst for many and varied reactions. Each Flowrence unit has been tailored for the specific purpose of catalyst screening, for example :

  • Flowrence 1220: Ethanol, methanol, glycerol and methane reforming, deNOx.
  • Flowrence 1221: Propylene, alcohol and glycerol oxidation and glycerol or hexose valorisation.

Flowrence contains 4 temperature blocks, each one can be operated at different temperature. Each block can receive 4 stainless steel or quartz reactors, so 16 isothermal fixed bed micro flow reactors can run in parallel and 16 experiments can be conducted simultaneously. Between 50-500 mg of catalyst can be loaded in one reactor. Flowrence can operate at wide conditions range: pressure between atmospheric and 90 bars, temperature between 50°C and 750°C, feed can be either gas, liquid or trickle flow.

All Flowrence systems are equipped with 16 ports multi positions to analyze the gas effluent by online gas chromatograph, Agilent 7890.

Flowrences 1219 and 1221 are also equipped with a liquid sampling robot allowing the collection of the effluents from each reactor separately. The sampling robot temperature is controlled between 10-80°C using an external cooling - heating device. This prevents the evaporation of light compounds or the solidification of heavy compounds, as wax, composites that can be present in the effluent.

The reaction effluents can also be analyzed by off-line mode: by GC-FID FID, GC-FID-MS and HPLC-DAD-MS according to their nature.
