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 presente invencion se refiere a composiciones absorbentes, resistentes al desgaste para la remocion de azufre elemental y compuestos de azufre, tal como sulfuro de hidrogeno y sulfuros organicos, de gasolina de craqueo y diesel que se preparan por la impregnacion de un soporte absorbente que comprende oxido de zinc, perlita expandida, y alumina con un promotor tal como niquel, oxido de niquel o un precursor de oxido de zinc, seguido por la reduccion de las valencia del metal promotor en la composicion de soporte absorbente de metal promotor resultantes. |
