• Other setups are available.

Catalyst screening and Hydrogenations in reduced time, reproducible and safe: These were the key issues for our customer in chemical research, asking us to develop this system.

As a new Buchi product, this system needed to be configurable and modular to serve the different needs of our customers worldwide.

Modular Hardware:

• 2 - 6 Reactors PPR systems are available
• Individual or parallel operation settings for each reactor (temperature, other)
• Configurable hardware:  from Basic to complete setup including dosing
• Automated sampling

Operation modes:

• Manual: The software controls the reactor hardware, data logging of process data
• Automated: Low to high degree (full process automation including dosing of gas, liquids)
  For full automation, a recipe editor is included in the software to edit existing settings and to define completely new processes.

Multiple safety features guarantee safe hydrogenations and other processes

2 - 6 pressurized reaction vessels in its individual heating / cooling blocks can be controlled in the PPR system. The system is expandable, starting at 2 reactors.

• Reactor block with individual heating / cooling
• Lift for Reactor block lifting / lowering
• Individual temperature control
• Reactor with safety fast action closure
• Stirrer drive with powerful magnetic coupling (75 Ncm torque)
• Continuous adjustable agitator speed, 0-2500 rpm
• Safety rupture disc
• Pt100 sensor
• Cover with 6 opening (for Pt100, dip tube, valves, etc.)
• Optional burette, catalyst basket, gassing stirrer, others..
• Optional liquid dosing via balance (at up to 275 bar)
• Optional liquid dosing, SS316 pr PEEK corrosion resistant metering pump, flow rates 0.003 to 40 ml/min
