    摘要: The invention concerns high performance adsorbents based on activated carbon of high microporosity which are present in the form of discrete grains of activated carbon, preferably in spherical form, and which are characterized by the following parameters: a Gurvich total pore volume of at least 0.7 cm3/g, at least 70% of this total pore volume being formed by micropores having pore diameters of ≦20 Å, a measure of central tendency pore diameter of not more than 30 Å, and a BET surface area of at least 1500 m2/g. These high performance adsorbents are particularly useful for the adsorption of toxins, noxiants and odors, in particular from gas or to be more precise air streams, for purifying or cleaning gases, such as in particular air, for application in medicine or to be more precise pharmacy and as sorptive storage media for gases, in particular hydrogen.

    摘要: The invention has as subject matter a rotary tube, especially for a rotary tube kiln for the production of carbon, with several mixing elements arranged in the inner space of the rotary tube for a thorough mixing of a charged material. The rotary tube comprises a transitional area from a smaller inside cross section to a larger inside cross section of the rotary tube. The mixing elements are formed in the transitional area and/or are arranged in such a manner that the charged material is transported during operation by the mixing elements toward the smaller inside cross section. The result is an excellent thorough axial mixing and blending of the charged material, which results in an increased homogeneity of the activated carbon produced.
