Test Units for Process Intensification

Catalyst Test Units with Applied Catalysts

These Catalytic Test Units (CTUs) can be used for many specialty chemical processes, fine chemical and pharmaceutical chemistries, such as: hydrogenation, amination and dehydrochlorination. When used with Applied Catalysts activated carbon monolith catalysts (ACMC®), in addition to process intensification (high productivity), the advantages include: higher selectivity, better thermal management, and low pressure drop/low attrition. Three reactors systems have been designed for catalyst screening. The single catalyst testing unit, the multiple catalyst testing unit, and the catalyst lifetime/recycle reactor testing unit. The CTU systems feature gas phase uptake measurements and differential temperature measurements, which can be used as a first level screen of catalytic activity for hydrogenation and other chemistries where gas phase products are consumed.

        Product Brochure

Single Station Test Unit

A single catalyst can be tested in a 1.3 cm i.d. tube with 8 cm bed length, with liquid flow rates of 4 mL/min, temperatures of ambient to 250 ºC, and pressures of ambient to 100 bar.

Screening Reactor

A four reactor version of the Catalyst Screening reactor that allows for higher through-put screening.

Lifetime Reactor

A single catalyst can be tested in a 2.7 cm diameter tube with 30 cm bed length, with liquid recycle to simulate longer bed lengths at typical LHSV, P, T and with the capability to run 24/7 for lifetime studies. Liquid flow rates of 51 mL/min, temperatures of ambient to 250 °C, and pressures of ambient to 100 bar.

Features and References

Features

Flow, temperature, and pressure readings are all displayed and recorded on custom software with easy interface to a third-party trending/data program.

Safety features include:

• Pressure relief valves
• Normally closed valves after feed mass flow controllers
• PLC set temperature limits

Advanced features for high pressure, liquid level sensing, and recycle can be designed on a custom basis.
