Abstract:
Tight packing of an adsorbent in a sepn. column with a chamber >=1.83 m wide comprises firstly mixing the adsorbent with an excess of a conc. reagent which causes the adsorbent to contract reversibly in its presence. The adsorbent is then packed in the contracted state, into the chamber of the sepn. column and effectively enclosed. The excess reagent is then removed to cause the adsorbent to swell so that the chamber becomes fully and uniformly packed with the adsorbent particles. The process is esp. useful for preparing technical scale ion exchange units contg. e.g. Ca salts of cross linked ring-sulphonated polystyrene esin adsorbents used in the sepn. of mixed fructose- and dextrose sugar solns.
Abstract:
Non-compacting, annyd. dextrose conversion syrup product in particle form prepd. by shearing and cooling a molten dextrose conversion syrup (perfectly at 85-93% dry solids) to a temp. lower than 200≦̸F, deposition and solidifying the fluid mass upon a supporting member to an anhyd. dextrose product, granulating the solidified product and drying the particles to less than 2% moisture. The anhyd. dextrose particle have unique properties and may be used as a sugar or dextrose monohydrate replacement.
Abstract:
Anionic exchange resins exhibiting a reduced syrup refining capacity are rejuvenated to a useful state by treating the anionic exchange resins at a temperature of at least 170* F. with a concentrated acid solution for a period of time and under conditions sufficient to remove therefrom the occluded organic impurities which interfere with its anionic exchange capacity.
