Abstract
A process for preparing a naphtha reforming catalyst has been developed. The process involves the use of a chelating ligand such as ethylenediaminetetraacetic acid (EDTA). The aqueous solution of the chelating ligand and a tin compound is used to impregnate a support, e.g., alumina extrudates. A platinum-group metal is also an essential component of the catalyst. Rhenium may also be a component. A reforming process using the catalyst has enhanced yield, activity, and stability for conversion of naphtha into valuable gasoline and aromatic products.

1. A catalyst effective for naphtha reforming comprising a particulate refractory inorganic oxide support having distributed throughout a stannous tin component, a platinum-group metal component, and a rhenium component; the catalyst characterized in that the tin is uniformly distributed throughout the support and the platinum-group metal is uniformly distributed throughout the support; the tin being distributed throughout the support with an impregnation using a tin chelate complex.
2. The catalyst as claimed in claim 1 wherein the chelate is a chelating agent selected from the group consisting of ethylenediaminetetraacetic acid, nitrilotriacetic acid, N-methylaminodiacetic acid, iminodiacetic acid, glycine, alanine, sarcosine, .alpha.-aminoisobutyric acid, N,N-dimethylglycine, .alpha.,.beta.-diaminopropionate, aspartate, glutamate, histidine, and methionine

7. The catalyst as claimed in claims 1 to 5, or 6 wherein the platinum-group metal component is platinum, which is present in an amount of 0.01 to 2 mass-% on an elemental basis.
8. The catalyst as claimed in claims 1 to 6, or 7 wherein the rhenium component is present in an amount of 0.05 to 5 mass-% on an elemental basis.
9. The catalyst as claimed in claims 2 to 7, or 8 wherein the chelating agent and stannous tin compound are present in a ratio of 1 to 8.
10. A process for the catalytic reforming of a naphtha feedstock which comprises contacting the feedstock at reforming conditions with the catalyst as claimed in claims 1 to 8, or 9, wherein the reforming conditions comprise a temperature of 315°C
to 600°C, a pressure of 100 kPa to 7 MPa (abs), a liquid hourly space velocity of 0.1 to 20 hr-1, and a mole ratio of hydrogen to naphtha feedstock of 1 to 20.
