Abstract
Procedeu pentru regenerarea catalizatorilor de paladiu pe suport, folositi la oxacilarea olefinelor în faza gazoasa, caracterizata prin aceea ca, în scopul reactivarii executa tratarea acestora cu un amestec constituita din 80...99,9% de preferinta,90...99% dintr-un acid gras monocarboxilic alifatic saturat nesubstituit, cu cel mult 10 atomi de carbon în molecula, lichid în conditii normale si 0,1...20%, de preferinta, 1...10% oxizi de azot, preferabil cu continut de oxigen sau cu gaze continîndoxigen, acid azotic, peroxizi sau peracizi, de preferinta, acid azotic, dupa care catalizatorii respectivi se usuca, de preferinta, la presiune scazuta si într-un curent de gaz inert, la o temperatura sub 90 degree C, un timp suficient pentru evaporarea ac idului gras, pîna la un continut rezidual mai mic de 8%.
