Abstract

Procedimento per la deidrogenazione di paraffine leggere, in particolare C2-C5, per ottenere le corrispondenti olefine comprendente il far reagire dette paraffine con un sistema catalitico contenente platino, stagno, un supporto di allumina ed eventualmente un elemento del gruppo dei lantani in un reattore a letto fluido, dove il calore necessario per la reazione viene ceduto da detto sistema catalitico come calore sensibile, operando ad una temperatura compresa fra, 500 e 700°C e ad una pressione fra 1 e 2 kg/cm2 ed il rigenerare detto sistema catalitico bruciando il coke depositatosi sulla superficie del sistema catalitico stesso, conducendo detta rigenerazione in aria e/o ossigeno, eventualmente aumentando la temperatura del sistema catalitico ai valori opportuni, cui segue la riduzione di detto sistema catalitico con un riducente.
