Abstract

Inventia se refera la un procedeu pentru îmbunatatirea activitatii catalizatorilor pe baza de oxizi metalici si telur utilizati pentru oxidarea, amoxidarea sau dehidrogenarea oxidativa a compusilor organici. Procedeul consta în încalzirea catalizatorilor împreuna cu un solid continînd telur la o temperatura pîna la 900 degree C într-o atmosfera gazoasa. Procedeul poate fi efectuat si aplicat nu numai la catalizatorii deteriorati si epuizati a caror activitate a fost deteriorata datorita utilizarii lor o perioada îndelungata de timp ci si la catalizatorii proaspeti. Procedeul se poate utiliza în pat fluidizat fara oprirea reactiei respective.
