Heat Removal from Reverse Flow Reactors Used in Methane Combustion

摘要: The idea of using Reverse Flow Reactors (RFR) for methane reduction in exhausts has been well elucidated the past. However, there are intricacies such operations to maintain ignited state reactor along with maintaining low outlet concentrations methane. This is especially true under rich feed conditions where combustion reactions liberate more heat leading possible catalyst deactivation. Under favourable conditions, it continuously extract from RFR system-this a viable way acceptable thermal and consequently retaining activity. paper elaborates upon optimal amount that can be removed system without losing sustainability while preventing overheating bed. A simple event based control strategy implemented switching inlet ports (flow reversal). Issues relating operation reverse flow reactors side feeding possibility extraction useful systems also discussed. Methane reaction continuous two dimensional heterogeneous model have employed this study. L'idee d'utiliser les reacteurs ecoulement inverse pour la du dans gaz d'echappement ete bien expliquee le passe. Il n'est toutefois pas si de telles maintenir l'etat d'allumage reacteur en meme temps que faibles sortie C'est particulierement vrai des d'alimentation riche ou liberent davantage chaleur ce qui peut conduire desactivation catalyseur. Dans favorables, il est retirer continuellement systeme − s'agit d'un moyen fiable thermiques acceptables et donc conserver l'activite On etudie cet article quantite optimale etre retiree sans perte durabilite tout empechant surchauffe lit catalytique. Une strategie controle reposant sur criteres simples appliquee permuter orifices d'entree (inversion debit). examine egalement aspects relies au fonctionnement avec alimentation laterale possibilite retrait utile tels systemes. La un modele heterogene bidimensionnel continu sont utilises cette etude.
