Abstract
Prezenta inventie se refera la un procedeu de recuperare a unui catalizator de rodiu utilizat la dezalchilarea alchilbenzenilor cu vapori de apa sau sau hidrogen, carora le-a scazut activitatea în urma otrîvirii cu sulf. Este descris procedeul de regenerare a catalizatorilor de rodiu uzati si otraviti cu sulf în procesul de dezalchilare a alchilbenzenilor sau a amestecurilor lor tehnice, cu vapori de apa sau hidrogen, cuprinzînd o faza de ardere a cocsului cu gaz ce contine oxigen si clorura de clor sau compusi organici clorurati în curent de hidrogen. Catalizatorul se trateaza suplimentar cu amoniac sau un compus de azot care în conditii de exploatare se descompune cu formare de amoniac, în prezenta a cel putin unuia din componentii cuprinti în grupa: apa, hidrogen, amestec azot-oxigen. Tratarea se poate efectua atît în faza lichida cît si în faza gazoasa la temperaturi cuprinse între 20 si 650 degree C si presiuni de 1...50 at. Inventia se poate utiliza pentru regenerarea catalizatorilor de rodiu utilizati în procesele de dezalchilare a alchilbenzenilor cu vapori de apa sau hidrogen.
