    • A feed gas which contains H.sub.2 S is combusted with oxygen and air in at least one burner, which opens into a combustion chamber. The resulting gas mixture contains H.sub.2 S and SO.sub.2 and is intended to be converted to elementary sulfur by the Claus process. The combustion chamber is supplied with oxygen through a central tube of the burner, with the H.sub.2 S-containing feed gas through a second tube, which coaxially surrounds the central tube, and with air through a coaxial outer tube. The feed gas supplied to the burner contains H.sub.2 S and at least 5% by volume hydrocarbons or CO.sub.2. Velocities of flow of oxygen of 50 to 250 m/sec. and of the H.sub.2 S-containing feed gas of 10 to 30 m/sec. are adjusted at the outlet of the burner. Temperatures in the range from 2000.degree. to 3000.degree. C. are generated in the core zone of the burner flame. A gas mixture which contains at least 2% by volume CO and at least 8% by volume H.sub.2 and is at temperatures from 1350.degree. to 1650.degree. C. is withdrawn from the combustion chamber.
    • 含有H 2 S的进料气体在至少一个燃烧器中与氧气和空气一起燃烧,该燃烧器通向燃烧室。 所得气体混合物含有H 2 S和SO 2,并且通过Claus方法将其转化成元素硫。 通过燃烧器的中心管将燃烧室供给氧气,含有H 2 S的进料气体通过同轴地围绕中心管的第二管和通过同轴外管的空气。 供给燃烧器的进料气体含有H 2 S和至少5体积%的烃或CO 2。 50至250米/秒的氧气流动速度。 和含有H 2 S的原料气体为10〜30m / sec。 在燃烧器出口处进行调节。 在燃烧器火焰的核心区域中产生在2000℃至3000℃范围内的温度。 含有至少2体积%CO和至少8体积%H 2并且处于1350℃至1650℃的温度的气体混合物从燃烧室中排出。

    • The present invention provides a wound treating agent in powder form based on a swellable organic polymer, which comprises a cross-linked polymer of a hydrophilic acrylic or methacrylic acid derivative, which polymer is permeated by a gellable polysaccharide and/or protein or polypeptide, the agent being obtainable by polymerizing a hydrophilic acrylic or methacrylic acid derivative in the presence of a dissolved, gellable polysaccharide and/or protein or polypeptide and of a cross-linking agent.The present invention also provides a process for the production of this wound treating agent, wherein a hydrophilic acrylic or methacrylic acid derivative is polymerized in an aqueous solution of a gellable polysaccharide and/or protein or polypeptide in the presence of a cross-linking agent and of a conventional polymerization initiator, to give a transparent gel which is dried and pulverized.
