Method for preparing fuel element for smoking article

摘要

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.

主权项

1. A fuel element in a form suitable for incorporation into a smoking article comprising a combustible carbonaceous material, a binder, and a metal-containing catalyst precursor or a catalytic metal compound produced by thermal decomposition of the metal-containing catalyst precursor, wherein the metal-containing catalyst precursor or catalytic metal compound are carried by particles of graphite or filler material within the fuel element.
