High-Performance Systems for Catalytic Reaction Studies and Continuous Process Development

The Seprex Fixed Bed Catalyst Reactors are precision-engineered systems designed for a wide range of heterogeneous catalytic processes in both laboratory and pilot scale. These reactors are ideal for gas-solid and liquid-solid reactions, where reactants flow through a stationary bed of catalyst. Built for versatility, reliability, and scalability, they support detailed kinetic studies, catalyst screening, and process optimization.

• Reactor Configuration:

  • Type: Tubular or column-type packed bed

  • Flow Mode: Upflow or downflow operation

  • Capacity: From 100 mL lab-scale units to 10 L pilot reactors

  • Catalyst Support: Quartz wool, sintered metal, or ceramic disks

  • Material of Construction: SS316L, Hastelloy, Inconel, or other alloy steels depending on feedstock and process chemistry

• Operating Parameters:

  • Temperature Range: Ambient to 600°C (multi-zone electrical heating with PID control)

  • Pressure Range: Full vacuum to 100 bar(g)

  • Flow Rates: Highly accurate gas and liquid feed systems using MFCs and HPLC/metering pumps

• Automation & Control:

  • Instrumentation: Real-time temperature, pressure, and DP monitoring across catalyst bed

  • Control System: Fully automated with PLC/SCADA integration for data logging, trend analysis, and recipe control

  • Safety: Over-pressure relief, inert gas purging, and emergency shutdown system

• Auxiliary Systems:

  • Feed Preheaters and multi-stream gas blending units

  • Online analyzers integration (GC, FTIR, TCD/FID)

  • Post-reactor cooling, gas-liquid separation, and condensate recovery systems

• Catalyst screening and performance testing

• Kinetic modeling and reaction mechanism studies

• Process intensification and scale-up

• Reactions such as:

  • Hydrogenation and dehydrogenation

  • Oxidation and combustion

  • Fischer–Tropsch synthesis

  • Steam or dry reforming of hydrocarbons

  • VOC abatement or gas purification

• Skid-mounted, plug-and-play system with rapid deployment

• Integrated with CFD and simulation support for optimized design

• Modular upgrades for multi-reactor testing or parallel screening

• Backed by Seprex pilot infrastructure for seamless scale-up to commercial units
