Technique to reduce the zeolite molecular sieve solubility in an aqueous system |
| abstract |
An improved process for separating a component from a feed mixture comprising an aqueous solution of a mixture of different components, such as a mixture of saccharides. In the process the mixture is contacted with a zeolite which selectively adsorbs a component from the feed mixture. The adsorbed component is then recovered by contacting the adsorbent with a desorbent material such as water to effect the desorption of the adsorbed component from the adsorbent. There is an undesirable tendency for the silicon constituent of the zeolite to dissolve in the aqueous system. The improvement to the process comprises the impregnation of the zeolite with a binder material comprising a water permeable organic polymer which substantially reduces the undesirable dissolution. The adsorbent is manufactured by mixing together powder of the zeolite, powders of the organic polymer binder, and a liquid organic solvent, extruding the mixture into an extrudate and drying the extrudate. |
