Abstract
Inventia se refera la un procedeu de recuperare a unui catalizator de tip fosfat de fier, utilizat în mod tipic pentru oxidehidrogenarea hidrocarburilor, constînd din supunerea catalizatorului unei atmosfere oxidante, de preferinta prin întreruperea fluxului de substante organice alimentate prin patul de catalizator, urmata de faza în care catalizatorul se supune unei atmosfere reducatoare, de preferinta prin injectare de substante organice de alimentare, în absenta oxigenului, peste catalizator. Metoda este descrisa în mod specific pentru cazul producerii de acid metacrilic prin oxidehidrogenarea acidului izobutiric.
