1279554 Regenerating hydrogenation catalysts INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 15 April 1970 [18 April 1969] 18020/70 Heading B1E [Also in Division C5] Reduced Ni or Co on SiO 2 catalysts which have been deactivated in the hydrogenation of hydrocarbons are regenerated by heating in an O-containing gas at 300-600‹C, contacting with liquid H 2 O at 0-250‹C and then with H 2 at 200-500‹C. At no stage in the regeneration is the catalyst contacted with an alkaline agent. The preferred O 2 -containing gas is air.
