    • In a process for eliminating impurities and undesirable components from gas mixtures by passing the mixture through an activated carbon-containing adsorber. Sulfur compounds including hydrogen sulfide are eliminated by increasing the oxygen contents of the gas mixture which contains at least oxygen and/or sulfur dioxide in addition to the hydrogen sulfide to an extent that a hydrogen sulfide oxygen molar ratio is obtained in the gas mixture which is between about 1:0.45 and 1:0.65. The process may also be carried out with two groups of adsorbers where in the first adsorber the elemental sulfur is eliminated in liquid form and where the remaining minor portion of sulfur in vaporous or mist-like form is then removed in the second group of adsorber or adsorbers by adsorption on the activated coal. The purified gas is then recovered from the adsorber or with two groups of adsorbers from the second group of adsorber or adsorbers and the activated carbon is subjected to periodic regeneration cycles.
    • 在通过将混合物通过含活性炭的吸附剂从气体混合物中除去杂质和不期望的组分的方法中。 包括硫化氢在内的硫化合物除了除了硫化氢之外还含有至少含有氧和/或二氧化硫的气体混合物的氧含量以在气体混合物中获得硫化氢氧摩尔比的程度来消除, 介于约1:0.45至1:0.65之间。 该方法也可以用两组吸附器进行,其中在第一吸附器中元素硫以液体形式被去除,然后在第二组吸附器中除去气态或雾状形式的剩余少部分硫, 通过吸附在活化煤上的吸附剂。 然后从吸附器中回收纯化气体,或者从第二组吸附器或吸附器中回收两组吸附剂,并对活性炭进行周期性再生循环。

    • A bottom for a fluidized bed conveyor is composed of a plurality of members provided with openings and located in contact with each other so that their points of contact are gas impermeable at least during operation of a fluidized bed. The openings may be formed as circumferentially closed holes and/or as laterally open recesses. The members may laterally abut against each other, or may be provided with interengaging lateral projections. The members may be located so that at cold temperatures small intermediate spaces remain therebetween, which spaces are closed during operation as a result of thermal expansion of the members under the action of high working temperatures. Bracing element or elements may be provided which urge the members toward one another.
    • 用于流化床输送机的底部由设置有开口并且彼此接触定位的多个构件组成,使得它们的接触点至少在流化床的操作期间是不透气的。 开口可以形成为周向闭合的孔和/或形成为侧向敞开的凹部。 构件可以横向抵靠彼此,或者可以设置有相互接合的横向突起。 构件可以被定位成使得在寒冷的温度下保持较小的中间空间,由于构件在高工作温度的作用下的热膨胀,操作期间该空间被封闭。 可以提供支撑元件或元件,其促使构件彼此朝向彼此。
