Definitions
- the invention relates to a method for adsorptive separation of carbon dioxide and water from a carbon dioxide and water-containing carbon monoxide and hydrogen-rich gas mixture.
- Such gas mixtures are also referred to as synthesis gas mixtures and as a rule further processed or treated in low-temperature decomposition.
- the invention relates to a method for adsorptive separation of carbon dioxide and methanol from a carbon dioxide and methanol-containing carbon monoxide and hydrogen-rich gas mixture.
- Object of the present invention is to provide generic method for adsorptive separation of carbon dioxide and water or carbon dioxide and methanol, which avoid the aforementioned disadvantages.
- a method for the adsorptive separation of carbon dioxide and water is proposed, which is characterized in that the carbon monoxide and hydrogen-rich gas mixture in a first, containing a silica gel adsorption of water and in a second, a molecular sieve-containing adsorption of Carbon dioxide is purified and the
- the inventive method for adsorptive separation of carbon dioxide and methanol is characterized in that the carbon monoxide and hydrogen-rich gas mixture is purified in a first, containing a silica gel adsorption of methanol and in a second molecular sieve containing an adsorption of carbon dioxide and the regeneration the two adsorption layers by means of a carbon monoxide-rich gas (mixture) it takes place, wherein the temperature of 70 to 150 0 C, preferably 90 to 110 0 C.
- the desired carbon dioxide purities can be achieved by means of the procedures according to the invention.
- the formation of the undesirable formic acid is considerably reduced, so that little or no damage to the molecular sieve used takes place; This has the consequence that the life of the molecular sieve used significantly extended.
- the inventive method allows energy savings, since the gas stream used for the regeneration now only at 70 to 150 or 90 to 110 0 C must be heated while it was heated in the known procedures to at least 150 0 C.
- the quantitative ratio between silica gel and molecular sieve will in practice be based on the operating temperature, the water content and the carbon dioxide content to be removed.
- the molecular sieve used in the second adsorption step is preferably a 4 A, 5 A or 13 X type, with the latter type having been found to be most suitable.
- the silica gel used in the first adsorption layer is - according to a further advantageous embodiment of the method according to the invention - a small-pored silica gel.
- the silica gel used in the first adsorption layer may be preceded by a splash-proof silica gel or a splash-proof activated clay as spray-water protection.
- the two adsorption layers or the adsorption materials used therefor are preferably arranged within an adsorber or adsorption container. It is also conceivable to realize both adsorption layers in two or more Adsorbem or Adsorptions alternem.
