1. Process for purifying liquid olefinic hydrocarbon charges incorporating propylene in particular and containing from 1 to 70 ppm of carbonyl sulphide, to remove the carbonyl sulphide, characterized by passing the liquid hydrocarbon charge, at a liquid hourly spatial velocity of between 0.2 and 15, over an absorbent material base on zinc oxide and a promoter selected from alumina, silico-aluminas, calcium oxide or mixtures thereof, the amount of the promoter not exceeding 15 % by weight of the absorbent material, and the specific surface area of the absorbent material being between 20 and 100 m**2g. |
