Abstract
Official abstract text for this publication.
A phosphorus modification of an FCC catalyst is provided by reducing the sodium content of the as formed catalyst, a first treatment with a phosphate solution, a second ammonium exchange to further reduce the sodium content of the phosphorus solution treated catalyst and a second treatment with a phosphate solution.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for modifying an FCC zeolite catalyst with phosphorous comprising: exchanging an as-crystalized catalyst with an ammonium salt, so as to provide the catalyst with a sodium content of less than about 2% by weight Na 2 O, treating the ammonium-exchanged catalyst with a first phosphate solution, sufficient to add 0.5 to 2% by weight P 2 O 5 on the catalyst, ammonium ion exchanging the phosphorous treated catalyst to yield a low sodium catalyst h…
