5000 Multiple Reactor System (MRS)

Model 5000 Multiple Reactor System, six 75 mL Vessels with Flat-Gaskets and Head-Mounted Valves, shown with included 4871 Process Controller.
The Parr Series 5000 Multiple Reactor System has been designed to provide an integrated system for running multiple reactions simul­taneously and applying the principles of high throughput experimentation to reactions con­ducted at elevated temperatures and pressures.
The principle features of the new instrument include:
  • Six reactors with internal stirring.
  • Operating pressures to 3000 psi.
  • Operating temperatures to 300 °C.
  • Individual temperature control.
  • Continuous individual pressure monitoring.
  • Computer control and data logging
  • Manifold system for rapid turn around and to allow two different input gases.
  • Volumes and reactor geometry designed for three phase reactions.
  • Flexible Control Software.
Stirred Batch Reaction Vessel
This multiple reaction system has been designed around a vessel with 75 mL total vol¬ume. This will accommodate between 15 and 40 mL of liquid reactants which is close to the mini¬mum volume appropriate for heterogeneous catalytic reactions.
Operating Modes
The Series 5000 Multiple Reaction System provides an apparatus for running up to six reactions in parallel to build a database for com¬paring and optimizing operating conditions. The user can design experiments to:
  • Run all reactions at the same temperature and pressure while varying catalyst loading or reactant concentrations to optimize these parameters.
  • Run all reactors with identical loads varying pressures at a common temperature to study the effect of pressure on reaction rates.
  • Run individual reactors with individual load¬ing and temperature and pressure to screen multiple options for activity.
A comparison of the plots of pressure drop versus time within the reactors running under parallel conditions will usually be the most useful means of measuring reaction rates and comparing operating conditions. The internal thermocouple also provides a means of detect¬ing temperature changes due to exothermic reactions.
