Low conversion is sometimes overcome using several adiabatic reactors with interstage cooling. Several reactors, with heat exchangers for cooling between them, are run up to near the maximum reaction rate until satisfactory conversion is attained. Methanol synthesis from syngas is a typical example where this technique is used: . This reaction is reversible at 250°C (the temperature where commercial reactors are operated). It is common to use interstage cooling to achieve high conversion and to extract reaction heat.
