Abstract
Official abstract text for this publication.
A metal trap for an FCC catalyst include pre-formed microspheres impregnated with a salt of calcium and/or magnesium and an organic acid salt of a rare earth element.
First claim
Opening claim text (preview).
What is claimed is: 1. A metal trap comprising pre-formed microspheres impregnated with a solution comprising an organic acid salt of a rare earth element and a salt of calcium and/or magnesium, wherein the pre-formed microspheres consist of calcined hydrous kaolin and the pre-formed microspheres have a pore volume of at least about 0.10 cm 3 /gram, wherein the pre-formed microspheres have a particle size of from about 40-150 microns. 2. The metal trap of claim 1 comprising at least 0.1 wt. % of the rare earth element on an oxide basis, and at least 0.1 wt. % of the calcium and/or magnesium on an oxide basis. 3. The metal trap of claim 1 comprising from about 1 wt % to about 20 wt % of the rare earth element on an oxide basis, and from about 1 wt % to about 6 wt % of the calcium and/or magnesium on an oxide basis. 4. The metal trap of claim 1 , wherein the rare earth element is lanthanum, cerium, ytterbium, gadolinium, yttrium, neodymium, or a mixture of any two or more thereof. 5. The metal trap of claim 1 , wherein the salt of calcium and/or magnesium is a salt of calcium. 6. The metal trap of claim 1 , wherein the organic acid salt is a formate, acetate, a propionate salt, or a mixture thereof. 7. The metal trap of claim 6 , wherein the organic acid salt of the rare earth element is lanthanum formate, lanthanum acetate, cerium formate, cerium acetate, or a mixture of any two or more thereof.
