  • Process for making a carbon heat source and smoking article including the heat source and a flavor generator
    Patent number: 5060676
    Abstract: The present invention relates to a process for producing a tasteless carbon heat source from a preformed article of a ligno-cellulosic material according to which the article is pyrolyzed in a continuously exchanged inert atmosphere at a temperature within the range of from about 800.degree. to about 1100.degree. C., for from about 0.5 to about 3 hours, then cooled in the inert atmosphere at a rate of from about 500.degree. to about 10.degree. C. per hour to a temperature within the range of from about 275.degree. C. to about 25.degree. C., and then subjected to at least one additional process step selected from an oxygen absorption step, a salt impregnation followed by heat treatment step, and a water desorption step. The present invention also relates to a smoking article including the carbon heat source, and a flavor generator comprising a substrate material containing at least one thermally releasable flavorant.
