Abstract

The present invention relates to a process of producing a metal-containing catalyst. The process involves mixing a support material with one or more metals in a solution to produce a catalyst comprising a metal-loaded support. The catalyst comprising a metal-loaded support is treated with an atmosphere comprising 0.01 to 100% carbon-containing agents and 0-100% hydrogen at a temperature of 50 to 500° C. to produce a treated metal-containing catalyst on a support. Also disclosed is the resulting treated metal-containing catalyst and its use in a process for converting propane to propylene.

First claim

What is claimed is:

1. A process of producing a platinum-tin catalyst, said process comprising:
mixing a support material with platinum and tin compounds in a solution to produce a catalyst comprising a platinum and tin-loaded support;
reducing the catalyst comprising the platinum and tin-loaded support in the presence of a reducing agent; and
treating the reduced catalyst in a gaseous atmosphere comprising 0.01 to 100% carbon-containing agents and 0-100% hydrogen at a temperature of 50 to 500° C. to produce a treated platinum-tin catalyst.

2. A process of producing a platinum-tin catalyst, said process comprising:
mixing a support material with platinum and tin compounds in a solution to produce a catalyst comprising a platinum and tin-loaded support;
reducing the catalyst comprising the platinum and tin-loaded support in the presence of hydrogen; and
treating the reduced catalyst in a gaseous atmosphere comprising 0.01 to 100% carbon-containing agents and 0-100% hydrogen at a temperature of 50 to 500° C. to produce a treated platinum-tin catalyst.
