A sorbent for use in removing sulfur contaminants from hydrocarbon feedstocks is provided, wherein the sorbent contains zinc aluminate in an amount of at least 40 wt% (calculated as ZnAl2O4); free alumina in an amount of from about 5 wt% to about 25wt% (calculated as Al2O3); and iron oxide in an amount of from about 10 wt% to about 30 wt% (calculated as Fe2O3); wherein each of the free alumina and iron oxide are present in non-crystalline form as determined by X-ray diffraction analysis, and a method for producing the sorbent and method for using the sorbent to reduce sulfur contaminants in hydrocarbon feedstocks.
L'invention porte sur un sorbant de désulfuration d'hydrocarbures contenant: de l'aluminate de zinc à raison d'au moins 40 % en poids (sous la forme de ZnAl2O4); de l'alumine libre à raison d'environ 5 à environ 25 % en poids (sous la forme de Al2O3); un oxyde de fer raison d'environ 10 à environ 30 % en poids (sous la forme de Fe2O3). L'alumine libre et l'oxyde de fer sont présents sous une forme non cristalline déterminée par analyse par diffraction de rayons X. L'invention porte également sur un procédé de production du sorbant et sur un procédé d'utilisation du sorbant pour la désulfuration d'hydrocarbures.
