Nutzen und Grenzen der Anwendung kinetischer Modelle für die Reaktorberechnung, dargestellt am Beispiel des Hochdruck-Polyäthylen-Verfahrens

open access: yesCHIMIA, 1974
The design of a reactor for complex reactions by means of the generally adapted balances of mass, energy and momentum is only possible if the reaction mechanism can be described by a kinetic model.
