Claims34
A method of providing and using a tobacco-derived pyrolysis oil, comprising:
- obtaining a tobacco material;
- pyrolyzing the tobacco material to produce char and a vapor product;
- separating the vapor product from the char;
- condensing and collecting the vapor product to give a tobacco-derived pyrolysis oil;
- adding the tobacco-derived pyrolysis oil or one or more isolated components of the tobacco-derived pyrolysis oil to a tobacco material or a non-tobacco plant material as a carrier for the tobacco-derived pyrolysis oil;
- and incorporating the tobacco material or non-tobacco plant material into a tobacco product.
A method of providing a tobacco-derived pyrolysis oil, comprising:
- obtaining a tobacco material;
- pyrolyzing the tobacco material to produce char and a vapor product;
- condensing and collecting the vapor product to give a tobacco-derived pyrolysis oil;
- and
- isolating a single component or mixture of components from the tobacco-derived pyrolysis oil, wherein the one or more components comprise vanillin, acetovanillin, guaiacol, 2, 6-dimethoxyphenol, or a combination thereof.
A method of providing and using a tobacco-derived pyrolysis oil, comprising:
- obtaining a tobacco material;
- pyrolyzing the tobacco material to produce char and a vapor product;
- condensing and collecting the vapor product to give a tobacco-derived pyrolysis oil;
- and
- incorporating the tobacco-derived pyrolysis oil into a tobacco product selected from the group consisting of a smoking article, a smokeless tobacco product, and an electronic smoking article.
A tobacco product incorporating a tobacco-derived pyrolysis oil comprising less than about 100 ppm benzo[a]pyrene, wherein the product is selected from the group consisting of a smoking article, a smokeless tobacco product, and an electronic smoking article.
