Abstract
Disclosed in certain embodiments is a sulfur tolerant catalytic system that includes a catalytic material coated onto a substrate. Certain embodiments are directed to a method of preparing a sulfur-tolerant catalyst.
Claims20
A method of preparing a sulfur-tolerant catalyst, the method comprising:
- impregnating a precious metal solution comprising platinum onto a sulfur-tolerant support material comprising silica on zirconia to form a slurry;
- coating a substrate with the slurry to form a coated substrate;
- drying the coated substrate;
- and
- calcining the coated substrate.

A method comprising:
- providing a catalytic system, wherein the catalytic system comprises:
- a catalytic material comprising:
- an active precious metal component comprising platinum;
- and
- a sulfur-tolerant support material comprising silica and zirconia mixture;
- and
- a substrate having the catalytic material coated thereon;
- placing the catalytic system in a stream containing carbon monoxide and high sulfur levels;
- and
- aging the stream containing high sulfur levels with the catalytic system, wherein the aging results in a carbon monoxide conversion greater than 80%.
