✦ Synopsis

Mechanismen wird der Kohlenstoff nach einem gewissen Profil niedergeschlagen : fallend fiir den Parallel Mechanismus, steigend fiir den Folgemechanismus. Die Folge des Bestehens solcher Profile in dem Kohlenstoffgehalt auf die Geschwindigkeitsund Temperaturprohle werden diskutiert. Es wird gezeigt, dass in Fall eines fallenden Profils im Kohlenstoffgehalt die Geschwindigkeit-und Temperaturprolile Spitzen zeigen, deren Platz sich im Reaktor verandert mit zunehmender Betriebsdauer. 1.

AbstractSince autothermal reactors are always operated in the ignited steady state, control measures must be taken to prevent the reactor from extinction during times of lean feed as well as from overheating during times of rich feed. Respective control measures are discussed for autothermal reactor
