  • Publication number: 20240172606
    Abstract: Some variations provide a biomedia composition comprising: from 50 wt % to 75 wt % total carbon, on a dry basis, according to ASTM D5373, wherein the total carbon is renewable according to ASTM D6866 (14C/12C isotopic ratio); from 20 wt % to 40 wt % oxygen, on a dry basis, according ASTM D5373; from 3 wt % to 10 wt % hydrogen, on a dry basis, according to ASTM D5373; and from 0.1 wt % to 2 wt % nitrogen, on a dry basis, according to ASTM D5373, wherein the biomedia composition is characterized by volatile-matter content from 50 wt % to 75 wt %, according to ASTM D3175; wherein the biomedia composition is characterized by ash content from 1 wt % to 25 wt %, according to ASTM D3174; and wherein the biomedia composition is characterized by moisture content from 0 to 75 wt %, according to ASTM D3173. Processes are also described to make and use the biomedia compositions.

  • Patent number: 11987763
    Abstract: Some variations provide a process for producing biocarbon pellets, comprising: pyrolyzing a biomass-containing feedstock in a first pyrolysis reactor to generate a first biogenic reagent and a pyrolysis vapor; introducing the pyrolysis vapor to a separation unit, to generate a pyrolysis precipitate in liquid or solid form; contacting the first biogenic reagent with the pyrolysis precipitate, thereby generating an intermediate material; pelletizing the intermediate material, to generate intermediate pellets; optionally, drying the intermediate pellets; separately pyrolyzing the intermediate pellets in a second pyrolysis reactor to generate a second biogenic reagent and a pyrolysis off-gas; and recovering the second biogenic reagent as biocarbon pellets. Some variations provide a similar process that utilizes a carbon-containing condensed-matter material, which is not necessarily a pyrolysis precipitate.

  • Publication number: 20220049546
    Abstract: A window shade system is presented that combines the benefits of roller shades with draperies. In one arrangement a fascia having a front plate and a bottom plate includes a track positioned in the forward lower end of the fascia. The fascia is configured to be attached to a plurality of brackets. One or more roller shades having roller shade material attached to a tube are connected to the brackets. A plurality of carriers are positioned in the track and one or more draperies are attached to the plurality of carriers in the track. This arrangement presents a dual functioning window shade wherein roller shade material may be opened and closed by raising and lowering the roller shade material by rotating the tube of the roller shades raised, and the drapery shade material may be opened and closed by sliding the drapery shade material along the length of the track.
