VERFAHREN ZUM HERABSETZEN DES ENERGIEVERBRAUCHS VON REAKTOREN FUER DIE HETEROGENEN KATALYTISCHEN SYNTHESEN.

摘要

The system for reducing energy consumption improving reactors for heterogeneous synthesis reactions, particularly for ammonia and methanol synthesis, in which the reaction gas flew axially through the catalyst bed(s) of said reactors, now involving the insertion in at least a part of the above catalyst beds of : two cylindrical substantially perforated walls for delimiting laterally the catalytic beds; a bottom closure diaphragm in between said cylindrical walls; an upper minor portion of at least one of said walls is unperforated and the reaction gas now flows substantially radially (inwardly or outwardly) through said beds. According to particular embodiments of the invention a diaphragm and/or a catalyst size gradient can be brought about on the top of at least one bed, said diaphragm being partially perforated or totally closed,
