Abstract: IN THE SELECTIVE HYDROGENATION OF HIGHLY UNSATURATED COMPOUNDS, SUCH AS ACETYLENES AND CONJUGATED OLEFINS, TO MONOETHYLENIC HYDROCARBONS, SAID RECATION BEING CONDUCTED AT ABOUT 0-250*C. IN THE PRESENCE OF A GROUP VIII METAL, THE CATALYST BECOMES DEACTIVATED BECAUSE OF THE DEPOSIT OF POLYMERIC OR RUBBERY-LIKE MATERIAL, AND SOMETIMES IT IS POISIONED BY SULFUROUS IMPURITIES. THE CATALYST IS RECATIVATED BY WASHING IT WITH INERT LIQUID HYDROCARBON AT BELOW 200*C., AND IN SUBSEQUENT STEPS, SEPARATING THE WASHED CATALYST FROM THE LIQUID, AND THEN CONTACTING THE SEPARATED CATALYST WITH HYDROGEN AT 200-500*C.
