Abstract
Smoking article include a smokable material and an activated carbon particle downstream of the smokable material. The activated carbon particle is produced from a whole seed. The activated carbon particle has a length, width and height. At least two of the length width and height are independently in a range from about 1 mm to about 7.5 mm. The particles can be spheroids, in which case the length, width and height would be the same or similar.
Claims15
A smoking article comprising:
- a smokable material;
- and
- an activated carbon particle downstream of the smokable material, the activated carbon particle produced from a whole seed without mechanical disruption, wherein the activated carbon particle has a length, width, and height, wherein at least two of the length, the width and the height are independently in a range from 1 mm to 7.5 mm wherein the whole seed is selected from achira seeds, amapola or poppy seeds, amaranto or amaranth seeds, mijo or millet seeds, mostaza or mustard seeds, pimiento Negra or black pepper seeds, palmera or palm seeds, aladierno seeds, bayon seeds, ginebre or juniper seeds, sabina seeds and falsa pimiento or false pepper seeds, or a combination.
A method for manufacturing a filter for a smoking article, comprising:
- carbonizing and activating a whole seed selected from achira seeds, amapola or poppy seeds, amaranto or amaranth seeds, mijo or millet seeds, mostaza or mustard seeds, pimiento Negra or black pepper seeds, palmera or palm seeds, aladierno seeds, bayon seeds, ginebre or juniper seeds, sabina seeds and falsa pimiento or false pepper seeds, or a combination, the whole seed having a length, width and height,
- wherein at least two of the length, width and height are independently in a range from 1 mm to 10 mm to form an activated carbon particle from the whole seed without mechanical disruption;
- and
- incorporating without mechanical disruption the activated carbon particle into the filter.
