PROCEDE DE SYNTHESE CATALYTIQUE HETEROGENE, EN PHASE GAZEUSE SOUS HAUTE PRESSION ET REACTEUR DE MISE EN OEUVRE

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.
