An aerosol-generating article is provided, including: a fluid guide having proximal and distal ends, and an inner longitudinal region including an inner longitudinal passageway between the distal end and the proximal end thereof, such that fluid can travel from the distal end to the proximal end, the fluid guide including a barrier between the inner and outer longitudinal passageways; a tubular element including a gel or a porous medium or a thread loaded or any combination, the gel or the medium or the thread or the combination includes an active agent, the tubular element having proximal and distal ends and disposed to a distal side of the fluid guide; an aperture to allow fluid to pass to the tubular element and exit the article at the proximal end; a combustible heat source at the distal end of the article; and a cavity between the fluid guide and the tubular element.

A disposable inhalation device that releases smoke which is not directly inhaled is provided. The body of the device is in the form of a cylinder formed by a sheath of thin material and is composed of three components that function independently of one another: an inhalation section, organic matter combustion section and a splitting section. The splitting section separates the inhalation section and the organic matter combustion section. Through the side apertures on the body of the inhalation section, the external atmospheric air enters the inhalation section during the inhalation process, where it mixes with the inhalation substance and the person inhales. By combustion of the organic matter together with the sheath of the organic matter combustion section, smoke is not inhaled directly by the inhaler i.e. the person who is inhaling.

A smoking article is provided, including a carbonaceous combustible heat source, an aerosol-forming substrate, and a wrapper circumscribing at least the heat source and the aerosol-forming substrate. One or more heat conducting elements overlie a rear portion of the heat source and an adjacent front portion of the aerosol-forming substrate. At least one heat conducting element includes a patch of thermally conductive printable medium printed onto the wrapper. Also provided is a method for applying heat conducting patches onto a web of smoking article wrapper material, wherein at least some of the patches include an area of thermally conductive printable medium.

The method and apparatus for manufacturing aerosol-generating semi-finished products comprise the steps of combining substantially cylindrical segments along a longitudinal first motion path. The following steps are performed along the first motion path: feeding a stream of at least three different segments along the first motion path, thereby arranging the at least three segments in alternating order, wrapping the stream of at least three segments in a sheet material to form an endless rod of segments, and cutting the endless rod of segments, thereby separating the endless rod of segments into wrapped segment rods. The method also comprises the step of processing wrapped segment rods along a second motion path, wherein the following step is performed along the second motion path: receiving the wrapped segment rods in flutes of a fluted receiving drum, wherein an end of the first motion path is aligned with a longitudinal axis of the flutes of the fluted receiving drum.

The method for intermediately storing double-length substantially cylindrical semi-finished products comprises the step of providing a tipping apparatus and forming double-length substantially cylindrical semi-finished products in the tipping apparatus. The method further comprises the steps of providing a cutting device and cutting the double-length semi-finished product into single products with the cutting device and providing a packer and packing single products in the packer. The method yet further comprises the steps of transporting the double-length semi-finished products from the tipping apparatus to the cutting device and transporting the single products from the cutting device to the packer, and intermediately buffering double-length substantially cylindrical semi-finished products in a buffer arranged between the tipping apparatus and the cutting device.

A smoking article is provided that includes an aerogel, which can be optionally impregnated with a catalytic metal compound or can optionally be coated with at least one aerosol-forming material and a flavoring agent. The smoking article comprises various segments such as a heat generation segment, an aerosol-generation segment, and a mouth end. The aerogel can be placed near or within any of these segments.

The presence of the aerogel can reduce the concentration of certain gaseous components of mainstream smoke generated during use of a smoking article incorporating a heat generation segment containing a fuel element.

There is provided a method of manufacturing a combustible heat source having a barrier, the method including providing a mold defining a cavity; placing a particulate component in the mold cavity; placing a laminar component, adjacent the mold, to cover the cavity opening; and compressing the particulate component to form the combustible heat source, wherein, during the compression step, the barrier is formed by punching the laminar component using a punch and the mold, the punch acting on the barrier to compress the particulate component and affix the barrier to the combustible heat source.

A modified carbon material, including a carbonaceous material and a water-insoluble modifier combined with the carbonaceous material, wherein the water-insoluble modifier is CuO, the carbonaceous material is one of or a mixture of biomass carbon or carbon black, a mass of the water-insoluble modifier is being 0.1-10 wt % of the carbonaceous material. The method for preparing the modified carbon material includes: (1) soaking the carbonaceous material in a copper sulfate solution for 5 to 36 hours, and (2) adding an alkali solution into a solution obtained in step (1) to provide a pH value ≥12, and after keeping the pH value for 0.5 to 2 hours, filtering and drying to obtain a solid. (3) using the carbonaceous material as a combustion heat source to reduce the ignition temperature, increase or reduce the peak thermal power temperature.
