Abstract

Μία διεργασία για την οξείδωση σε σταθερή κλίνη μεθανόλης σε φορμαλδεΰδη όπου η κλίνη περιλαμβάνει τουλάχιστον δύο στρώσεις που διαθέτουν διαφορετική καταλυτική δραστικότητα, όπου η στρώση χαμηλότερης δραστικότητας περιλαμβάνεται στο μέρος της κλίνης εκ του οποίου εισέρχεται το μείγμα αντιδρώντος αερίου, και η δραστικότητα της βαθμονομείται ούτως ώστε η μέγιστη θερμοκρασία θερμού σημείου στη στρώση να περιλαμβάνεται μεταξύ 350°C και 430°C και να είναι υψηλότερη από τη μέγιστη θερμοκρασία θερμού σημείου της στρώσης μεγαλύτερης δραστικότητας η οποία διαμορφώνεται από καθαρό καταλύτη, και όπου κατά τη διάρκεια της περιόδου κατά την οποία η κατάσταση της μέγιστης θερμοκρασίας θερμού σημείου της στρώσης χαμηλότερης δραστικότητας παραμένει στις τιμές που παρατίθενται ανωτέρω, η μετατροπή της μεθανόλης είναι υψηλότερη από 96% κατά mol.
