ABSTRACT:
In a reactor suitable for gas-phase catalytic exothermic synthesis, in particular of ammonia or methanol the synthesis gas is reacted in an upstream adiabatic catalytic zone, is cooled in a heat exchanger and then reacted further in a downstream catalytic zone, whereafter preferably it is cooled again, suitably in a boiler or feed water heater, and reacted further in a further catalytic zone. The gas flow through the catalyst is mainly in an axial direction and the pressure drop is kept low by disposing the catalyst in each zone in a plurality of beds fed in parallel from an inlet header and delivered in parallel into an outlet header. The beds may be separately removable from the reactor to facilitate catalyst charging and discharging.
