Claims
- 1. Zeolite L particles bound together with a zeolite binder which contains less than 10 percent by weight non-zeolitic binder, said particles comprising a plurality of cylindrical zeolite L crystallites with a mean diameter of at least 0.05 micron.
- 2. The zeolite L particles of claim 1 wherein the mean diameter of said zeolite L crystallites is at least 0.1 micron.
- 3. The zeolite L particles of claim 1 wherein said zeolite binder contains less than 5 percent by weight of non-zeolitic binder.
- 4. The zeolite L particles of claim 3 wherein said cylindrical zeolite L crystallites have basal planes shaped such that the ratio of axial length of the curved cylindrical surface to the overall axial length of the crystallite is greater than 0.9.
- 5. The zeolite L particles of claim 1 wherein said zeolite binder is substantially free of non-zeolitic binder.
- 6. The zeolite L particles of claim 1 further comprising a catalytically active metal.
- 7. The zeolite L particles of claim 5 wherein said catalytically active metal is a Group VIII metal.
- 8. The zeolite L particles of claim 6 wherein said catalytically active metal is present in an amount in the range of from about 0.1 to about 6.0 weight percent based on the weight of said particles and said catalytically active metal.
- 9. The zeolite L particles of claim 7 wherein said catalytically active metal is platinum, palladium, or mixtures thereof.
- 10. A catalyst comprising binderless zeolite L particles comprising cylindrical zeolite L crystallites with a mean diameter of at least 0.05 micron in a zeolite L matrix and a catalytically-active metal.
