Patent ID: 8597407

Claim:
A process for removing impurities from water-comprising gas streams which comprises contacting the water-comprising gas streams with adsorbents comprising oxides of elements selected from the group consisting of Cu, Fe, Zn, Ni, Co, Mn, Mg, Ba, Zr, Ce, La and combinations of these elements, which adsorbents have a copper oxide content of at least 30% by weight and have pore volumes of less than 0.175 ml·g −1 for pores having a radius of less than 20 nm which adsorbents are obtained by a process comprising the following steps: a) producing a solution of the components of an adsorption mass and/or of soluble starting compounds thereof, b) precipitating a solid from the solution by adding a base, c) separating off the precipitated product, d) washing the precipitated product, e) drying the precipitated product, f) calcining the precipitated product to form a pretreated powder, g) precompacting and tableting the pretreated powder to give tablets, and h) recalcination of the tablets at a temperature up to 650° C.
