    • Inorganic, porous particles filter a substance or substances from a flow of fluid such as a gas. The particles can be arranged into a bed to filter a substance (filtrate substance) from a fluid. The filtrate substance can collect on or within the pores of the inorganic particles. Collection of the filtrate substance within the pores of the particles rather than within the interstices of the bed enhances the filtering capacity and does not impede the flow of fluid through the bed of particles. Furthermore, the inorganic particles are re-usable, in that they can be subjected to harsh filtrate-separation techniques, e.g., heat treatment, solvent extraction, detergent washing, and centrifugal separation, yet retain their desired properties.
    • 无机多孔颗粒从诸如气体的流体流中过滤物质或物质。 颗粒可以布置在床中以从流体中过滤物质(滤液物质)。 滤液物质可以收集在无机颗粒的孔内或内。 在颗粒的孔内而不是在床的间隙内收集滤液物质增强了过滤能力,并且不阻碍流过颗粒床的流体流动。 此外,无机颗粒可重复使用,因为它们可以经受苛刻的滤液分离技术,例如热处理,溶剂萃取,洗涤剂洗涤和离心分离,但保持其所需的性质。

    • Buoyant, sphere-like materials on the order of about 10 to about 300 microns and surrounded, at least in part, by (1) a variable blend of a ferromagnetic and paramagnetic material and (2) an absorbing or adsorbing material are effective vehicles for isolating targeted materials. By virtue of its relatively low density, the composite material is capable of remaining sufficiently suspended in solution for a suitable amount of time. In addition, the blend of ferromagnetic and paramagnetic materials allows for the isolation of a composite material from an environment such as a solution, yet discourages substantial self-attachment of the composite materials in solution, when subject to a magnetic field. Accordingly, multiple embodiments of composite materials having these and other properties are disclosed, as well as methods for making and using the same.
    • 浮力的球形材料约为10至约300微米,并至少部分地通过(1)铁磁性和顺磁材料的可变共混物和(2)吸收或吸附材料而被包围的有效载体 隔离目标材料。 由于其相对低的密度,复合材料能够在适当的时间内保持充分悬浮在溶液中。 此外,铁磁材料和顺磁性材料的混合物允许从诸如溶液的环境中分离复合材料,但是当受到磁场的影响时,阻止复合材料在溶液中的显着自身附着。 因此,公开了具有这些和其它性质的复合材料的多个实施方案,以及制备和使用它们的方法。
