DESULFURIZATION AND SORBENTS FOR SAME

Attrition resistant, sorbent compositions for the removal of elemental sulfur and sulfur compounds, such as hydrogen sulfide and organic sulfides, from cracked-gasoline and diesel fuels are prepared by the impregnation of a sorbent support comprising zinc oxide, expanded perlite, and alumina with a...

Beschreibung
Zusammenfassung:	Attrition resistant, sorbent compositions for the removal of elemental sulfur and sulfur compounds, such as hydrogen sulfide and organic sulfides, from cracked-gasoline and diesel fuels are prepared by the impregnation of a sorbent support comprising zinc oxide, expanded perlite, and alumina with a promoter such as nickel, nickel oxide or a precursor of nickel oxide followed by reduction of the valence of the promoter metal in the resulting promoter metal sorbent support composition. La présente invention concerne des compositions de sorbants, résistant à l'attrition, et destinés à l'élimination du soufre et des composés soufrés (hydrogène sulfuré, sulfures organiques) des essences et gazoles de craquage. On prend un support sorbant à base d'oxyde de zinc, de perlite expansée, et d'alumine, et on l'imprègne d'un promoteur (nickel, oxyde de nickel, ou précurseur d'oxyde de nickel), puis on effectue une réduction de la valence du métal promoteur dans la composition de support sorbant à métal promoteur ainsi obtenue.
