Abstract: A catalyst bed combination comprising a bed of a particulate copper-containing catalyst and, upstream of the catalyst bed, a guard bed in the form of shaped units formed from lead oxide particles and a particulate support material. The guard bed extends the life of the copper catalyst by absorbing halide contaminants in the process stream.

Abstract: A method of an essentially complete elimination of remaining traces of mercury in gases, such as roaster gases containing SO2, and which have been treated in a chloride washer for removing elementary Hg,. It is characterized in that the gas is introduced to a scrubber plant where the same is washed with a washing liquid such that any content of gaseous HgCl2. The gas is absorbed by the washing liquid and is subjected to a turbulent and mechanical action in the scrubber so as to physically put together any Hg, HgCl2 and Hg2Cl2 and other compounds of Hg present in particle or drop form into bigger aggregates or agglomerates. Thus formed aggregates or agglomerates and present bigger particles are brought to be separated from the gas and then be collected and removed. The invention may be completed with further steps for the elimination of any remaining mercury.

Abstract translation: 一种基本上完全消除气体中残留痕量汞的方法，例如含有SO 2的焙烧气体，并且已经在用于除去基本Hg的氯化物洗涤器中处理过。 其特征在于将气体引入洗涤器设备，其中洗涤器用洗涤液洗涤，使得任何含量的气态HgCl 2。 气体被洗涤液体吸收，并在洗涤器中受到湍流和机械作用，从而物理地将任何Hg，HgCl 2和Hg 2 Cl 2以及其它以颗粒或液滴形式存在的Hg化合物组合成更大的聚集体或附聚物。 将这样形成的聚集体或附聚物和存在较大的颗粒与气体分离，然后被收集和除去。 本发明可以通过进一步的步骤来完成，以消除任何剩余的汞。
