Exothermal heterogeneous high-pressure synthesis process in the gas phase, and reactor for carrying it out.

摘要

According to the process using at least one catalyst bed in which the gases travel in a radial centrifugal manner, each catalyst bed (20) consists of at least two reaction zones: a central adiabatic zone and a peripheral zone subjected to cooling (5); the catalyst bed may be divided into a number of concentric, alternately adiabatic and cooled, zones. Application of the process especially to the syntheses of ammonia and of methanol.
