  • Method for rejuvenating solid paraxylene adsorbent
    Patent number: 6284695
    Abstract: The method for rejuvenating solid paraxylene adsorbent comprises the steps of varying the water injection rate above a predetermined minimum level in a non-linear fashion for a time sufficient to produce rejuvenation of the adsorbent and if desired, adding at least one polar organic compound to the water being injected.

  • Recovery of heavy metals from solution by extraction with cross-linked vegetable protein
    Patent number: 4355137
    Abstract: The present invention relates to a method of abstracting heavy metal ions from solution by contacting the solution containing heavy metal ions with a cross-linked vegetable protein, or a mixture of cross-linked vegetable proteins. The method may be used to separate a mixture of heavy metal ions in solution by selectively abstracting a particular heavy metal ion by contacting the particular heavy metal ion with a selected cross-linked vegetable protein.Preferred vegetable proteins are derived from wheat, rape seed, safflower seed, sun-flower seed or soya bean.
