Abstract

See full text

The invention provides a method for making a fuel element for a smoking article including the steps of mixing a metal-containing catalyst precursor with a filler material or graphite or a combination thereof to form a pre-treated fuel element component; optionally calcining the pre-treated fuel element component in order to convert the catalyst precursor to a catalytic metal compound; after the optional calcining step, combining the pre-treated fuel element component with a carbonaceous material and a binder to produce a fuel element composition; and forming the fuel element composition into a fuel element adapted for use in a smoking article. Examples of metal-containing catalyst precursors include iron nitrate, copper nitrate, cerium nitrate, cerium ammonium nitrate, manganese nitrate, magnesium nitrate, and zinc nitrate. Fuel elements treated according to the invention, and smoking articles including such fuel elements, are also provided.
