Abstract
The present invention relates to a method of treating a catalyst made from SiC substrates. The method includes subjecting the catalyst made from SiC substrates in the presence of at least a fluxing agent to heat from a flame generated from oxyfuel gas flowing from the lance, thereby resulting in the oxidation of the SiC bearing material.
Claims26
A method of treating a SiC bearing material containing PGMs, the method including:
- feeding feed material into a melt pool comprising essentially of slag contained in a vessel, wherein the feed material includes the SiC bearing material along with at least a fluxing agent and excludes a carrier metal or a sulfide matte;
- and
- delivering an oxygen carrying gas and a fuel gas into the vessel above the melt pool to generate a flame inside the vessel, wherein the flame is generated above the melt pool and is arranged to provide heat to oxidize the SiC bearing material, thus forming a carbon containing gas and slag containing the PGMs.
24-31. (canceled)
A method of treating a SiC bearing material supporting a catalyst, wherein the catalyst contains PGMs, the method comprising subjecting the SiC bearing material supporting the catalyst, in the presence of at least a fluxing agent and in the absence of a carrier metal and/or sulfide matte, to heat and/or a flame generated from the combustion of an oxygen carrying gas and fuel gas, thereby resulting in the oxidation of the SiC bearing material supporting the catalyst, and thus forming a slag containing PGMs and a carbon containing gas.
