Definitions

  • Mercury is a contaminant in many streams. Often these are streams that occur in the course of processing or burning fossil fuels or waste, as fossil fuels such as crude oil, natural gas or coal or waste contain traces of mercury in elemental or usually organically bound form. There are also mercury contaminant streams from processes in which mercury is used, for example the electrolysis hydrogen produced in the chlorine production by the amalgam process. Due to the high toxicity of mercury, it is usually necessary to remove mercury from such streams. Mercury may also corrode aluminum workpieces by amalgamating aluminum to destroy its surface oxide layer so that flows of material passing through aluminum apparatus or containers must be virtually free of mercury.
  • a silver and alumina-containing absorption mass was found, which is characterized in that the alumina is at least 50 wt .-% theta-alumina. Furthermore, a process has been found for the removal of impurities from streams by contacting them with an absorption mass which is characterized in that the absorption mass according to the invention is used.
  • an absorption mass consisting essentially of silver and / or silver oxide and alumina, that is, an absorption mass which, except for unavoidable impurities or insignificant amounts, does not contain portions other than alumina, silver or silver oxide.
  • an absorption mass which substantially (that is, except for unavoidable impurities, by-products from the production or constituents which show no effect in the inventive use of the absorption mass) of silver oxide Ag2 ⁇ on theta-alumina.
  • the BET surface area of the absorption mass of the invention is at least 1 m 2 / g, preferably at least 5 m 2 / g and more preferably at least 10 m 2 / g and at most 500 m 2 / g, preferably at most 400 m 2 / g and most preferably at most 300 m 2 / g.
  • the BET surface area is in the range of 30 to 120 m 2 / g, in the range of 40 to 100 m 2 / g or in the range of 60-90 m 2 / g.
  • the usual method for measuring BET surfaces is known, usually the one-point method with nitrogen is used based on DIN 66132.
  • the shaped bodies are converted by calcination into a finished carrier.
  • the calcination temperature is in the range of 900 ° C to 1100 ° C, preferably in the range of 950 ° C to 1050 ° C, and most preferably in the range of 980 ° C to 1030 ° C.
  • the calcination time is generally between 0.5 and 5 hours, preferably between 1 and 4 hours, and most preferably between 1, 5 and 3 hours.
  • the calcination takes place in a conventional furnace, for example in a rotary kiln, in a belt calciner or in a chamber furnace.
  • the calcination can be followed directly by the drying without intermediate cooling of the moldings.
  • the BET surface area and the pore volume are adjusted by known methods (in particular using finely divided or coarser starting materials, calcination time and temperature).
  • the silver to be deposited on the support and further constituents can be applied to the support by any known method, for example by coating from the gas phase (chemical or physical vapor deposition).
  • the preferred method is the impregnation with a solution of the substances to be deposited and / or compounds, which convert in the course of further processing in the substances to be deposited.
  • the individual substances to be deposited can be deposited individually and / or in partial quantities in several process steps or jointly and completely in one process step.
  • the co-deposition is in a impregnation step.
  • the absorption mass is prepared in a conventional manner by calcination.
  • This calcination essentially serves to convert the impregnated salts into the components or precursors of such components to be deposited, and differs from the above-described calcination, which serves for the preparation of the support material and the support structure.
  • this calcination essentially decomposes the nitrates into metals and / or metal oxides remaining in the catalyst and nitrous gases which escape.
  • Silver nitrate decomposes to silver oxide
  • the absorption mass After calcination, the absorption mass is basically ready for use. If desired, it is activated by pre-reduction prior to its use in a known manner and, if appropriate, also passivated on the surface again.
