BenchCAT Bench-top Reactor for Catalytic Studies

The μBenchCAT by Altamira Instruments represents a complete, bench-top reactor for catalytic studies. All the components required for either gas-phase or liquid-phase reaction studies are contained in a fully automated compact package. A variety of options makes the μBenchCAT suitable for a wide range of studies.

Reactor Feed: Up to 6 gases and 2 liquids can be used in the standard configuration of the μBenchCAT. Each gas train incorporates a filter, electronic mass flow controller (MFC), check valve, and positive shut-off valve. The range and gas calibration of each MFC is specified by the customer. Liquids are delivered using high precision HPLC pumps.

Condenser: A tube-in-tube condenser is located outside the oven at the outlet of the reactor. A thermocouple is used to monitor the coolant return.
Gas/Liquid Separator: The gas/liquid separator is found downstream of the condenser. Two level switches (high and low) activate an automatic valve and serve to maintain level control.
Pressure Control: Exit pressure is measured with a separate pressure transducer and the pressure is controlled using an automatic tapered needle valve.
Product Sampling Valve: An optional product sampling valve can be used to route an effluent sample to an external analytical device.

Heated Oven: Most process components are housed inside an isothermal oven operated at up to 200°C.

The following components are found in the heated oven:

• Integral gas preheater and liquid preheater/vaporizer operating at up to 300°C
• Feed mixer
• Reactor by-pass valves
• Reactor furnace with measuring and safety-switch thermocouples
• Reactor with internal thermocouple
• Pressure transducer isolator
• Lines leading to pressure transducer and pressure relief valve
mounted outside the oven.
