Sorbent compositions for the removal of sulfur and sulfur compounds, such as hydrogen sulfide, carbonyl sulfide and mercaptans, out of cracked gasoline and diesel fuels are prepared by impregnation of a sorbent support containing zinc oxide, expanded perlite and alumina with a promotor metal, such as nickel and/or cobalt, followed by reduction of the valence of the promotor metal. The use of milled expanded perlite in forming the sorbent support results in a support in which the zinc oxide content and binder content could be adjusted to provide an attrition resistant sorbent and extend the useful life of the sorbent.
Compositions de sorbants servant à extraire le soufre et les composés de soufre, tels que sulfure d'hydrogène, sulfure carbonyle et les mercaptans, de l'essence craquée et des combustibles diesel. On prépare ces compositions par imprégnation d'un support de sorbant contenant oxyde de zinc, perlite expansée et alumine par un métal promoteur, tel que nickel et/ou cobalt, puis par réduction de l'état de valence de ce métal promoteur. L'utilisation de perlite expansée broyée pour créer le support de sorbant permet d'obtenir un support dans lequel il serait possible de régler la teneur en oxyde de zinc et en liant, de manière à préparer un sorbant résistant à l'attrition et à prolonger la vie utile dudit sorbant.
