  • Publication number: 20230184427
    Abstract: The invention relates to a method of hydrogen gas combustion in an industrial furnace, wherein the hydrogen fuel gas composition is introduced into the cavity from the multi nozzle burner by a central flow of gas from at least one central gas nozzle with a simultaneous input of at least one independent further flow of the additional gas composition from at least one concentric gas nozzle, the central flow of gas of the hydrogen fuel gas composition is surrounded by a concentric flow of gas of a primary additional gas composition, the central flow of gas momentum per second of the hydrogen fuel gas composition at the exit of the central gas nozzle is in the range 0.001 - 1.2 [kgH2 m/s2] the concentric flow of gas momentum per second of the primary additional gas composition at the exit of the concentric gas nozzle is in the range 0.01 -10.4 [kgO2 m/s2] a ratio of a heating burner power (WCHEM [W]) to a hydrogen fuel gas composition kinetic power (WKIN [W]) is in the range WRATIO= 100.000 - 4.000.000 [1].

  • Patent number: 11427652
    Abstract: A chlorinated derivative of hyaluronic acid or of a modified hyaluronic acid (chloramide) is provided. The chloramide has an amidic group (—NH—CO—). The hydrogen of the amidic group is substituted by a chlorine atom, according to the structural formula —NCl—CO—. The substitution degree of the hyaluronic acid or of the modified hyaluronic acid by chlorine is in an amount of from 50 to 100 %.

  • Publication number: 20200179445
    Abstract: A composition having antimicrobial activity is provided. The composition comprises a polysaccharide, a stabilizer, and a triiodide, where the triiodide decomposition to iodide and volatile iodine can be significantly suppressed by the presence of the stabilizer. Methods of preparing and using the composition and devices prepared therewith are also disclosed. As compared to liquid forms comprising triiodide, stabilized solid forms can be used for a much wider range of applications due to their shape stability and a significantly smaller volume and weight of total material.
