摘要:
A method for binding impurities in paper production, comprising the following steps:a) provision of a bentonite, the proportion of the monovalent cations, based on the cation exchange capacity (CEC) of the bentonite, being at least 0.7 and the CEC being more than 85 meq/100 g, preferably more than 90 meq/100 g, in particular more than 95 meq/100 g;b) addition of the bentonite according to a) to a paper pulp or fiber suspension;c) binding of the impurities to the bentonite in the pulp or fiber suspensionis described.
摘要:
The invention relates to a process for producing granules and to a granule obtained by the process. In the process, a clay material is used which has a specific surface area of more than 150 m2/g, a pore volume of more than 0.45 ml/g and a cation exchange capacity of more than 15 meq/100 g.
摘要:
The invention relates to a method for separating proteins from liquid media, comprising providing a liquid medium containing proteins, providing a clay material which has: a specific surface greater than 150 m2/g, a pore volume greater than 0.35 ml/g, an ion exchange capacity greater than 40 meq/100 g, and a sediment volume in water of less than 15 ml/2 g, equilibrating said clay material to a pH of from 3.5 to 9.0, treating said liquid medium with the equilibrated clay material, and separating the purified, protein-depleted liquid medium from the clay material.
摘要:
The invention relates to a method for the sorption of at least one nucleic acid molecule from a liquid medium, comprising the following steps: (a) providing a liquid medium comprising at least one nucleic acid molecule; (b) providing a layer comprising at least one acid-activated phyllosilicate, where the layer is permeable by the liquid medium, and the layer thickness is at least 1 mm; (c) passing the liquid medium with the at least one nucleic acid molecule from step (a) through the layer from step (b) for sorption of the at least one nucleic acid molecule in the layer.
摘要:
What is described is a slurry comprising (a) at least 10% by weight of at least one sheet silicate, based on the total weight of the slurry; (b) an aqueous suspension medium and (c) a dispersing aid selected from at least one polyethylene glycol having a mean molecular weight of less than 90 000 and/or at least one polyacrylic acid in free acid form. Also described is a process for producing the slurry and the preferred used thereof.
摘要:
The invention relates to an adsorbent comprising a clay material and activated carbon. Further the invention relates to an animal feed comprising such adsorbent and to the use of such adsorbent for the adsorption of microbial toxins, in particular mycotoxins.

Applicants have amended the original Application, as filed, to include the appropriate arrangement of the specification, with titles for the appropriate sections, as suggested by the Examiner on pages 3 and 4 of the Advisory Action. No new subject matter is introduced by any of these amendments.
摘要:
A process for obtaining white sugar from e.g. sugar cane by treating the crude sugar juice with acid activated bentonite preferably selected from the group of smectites, whereby the acid activated bentonite mixture replaces the traditional environmental unfriendly sulfitation process. The acid-activated clay together with polyaluminium salts, and preferably phosphoric and/or sulfuric acid allows obtaining a high quality white sugar.
