Selecting a thermal catalysis reactor means satisfying two specifications at once: the chemistry's process conditions and the laboratory's safety obligations. This checklist organizes the decision along four lines, pressure, temperature, gas and path design, because a rig that meets the process but fails the safety case is not a solution.
Rate every wetted component above the maximum operating pressure plus margin; verify the relief chain, valve plus vent routed to a safe place; and confirm the pressure test regime after maintenance. For reactive gases, check material compatibility, not just strength.
Select heating range with headroom, not at the limit; verify temperature measurement at the bed, not the wall; and confirm uniformity over the catalyst zone. Rapid-heating needs power control with a defined failure mode, safe default is power-off.
Mass-flow controllers with the right calibration gas; check valves on every supply line to prevent back-feeding; purge capability with inert gas; and detectors or monitors appropriate to the hazards, hydrogen, CO, flammables. Toxic or flammable venting must never re-enter the workspace.
Minimize dead volume, keep heated lines above dew points, choose seal materials rated for the temperature and chemistry, and arrange the rig so leaks are visible and catchable, not hidden behind panels. The best rigs fail loudly and safely.
Write the process case and the safety case as two columns; a candidate reactor must pass both before price enters the conversation.
