Abstract
A desulfurization catalyst includes at least: 1) a sulfur-storing metal oxide, 2) an inorganic binder, 3) a wear-resistant component, and 4) an active metal component. The sulfur-storing metal is one or more of a metal of Group IIB of the periodic table, a metal of Group VB of the periodic table, and a metal of Group VIB of the periodic table, e.g., zinc. The desulfurization catalyst has a good stability and a high desulfurization activity.
Claims20
A desulfurization catalyst, comprising:
- 1) a sulfur-storing metal oxide, wherein the sulfur-storing metal is one or more selected from the group consisting of Group IIB metals, Group VB metals, and Group VIB metals;
- 2) an inorganic binder that is one or more selected from the group consisting of refractory inorganic oxides;
- 3) a wear-resistant component that is boron nitride or a combination of boron nitride with a compound other than boron nitride selected from the group consisting of oxides, nitrides, carbides, oxynitrides, carbonitrides, oxycarbides and oxycarbonitrides of an element A, wherein the element A is one or more selected from the group consisting of Group IVB metals, boron, aluminum, and silicon;
- 4) an active metal component selected from the group consisting of Group VIII metals, oxides of iron-group elements, Group IB metals, oxides of Group IB metals, Group VIIB metals and oxides of Group VIIB metals;
- and
- 5) optionally, an acidic porous material selected from the group consisting of molecular sieves and pillared clays.
