Abstract: A method for producing an iron-containing sorption material for treating feed water or waste water in order to remove harmful trace constituents by adsorption. To this end, an iron-containing solution is initially dehydrated in order to increase the salt content and transformed into a suspension of iron-containing solids from which the sorption material is obtained. By subsequently increasing the pressure of the suspension at a temperature of less than −5° C., the iron-containing solids in the suspension are transformed to dimensionally stable solid complexes. The iron-complex containing particles significantly facilitate treatment of water to remove hazardous trace materials because they provide a large surface area for carrying out the adsorption, yet filters made of this material do not become clogged even when treating heavily polluted waste water. In addition, the use of the sorption material of the invention makes it possible to dispense with use of fillers and/or auxiliary filter materials.

Abstract: A method for producing regenerable sulfur sorbents in which a support material precursor is mixed with isopropanol and a first portion of deionized water at an elevated temperature to form a sol mixture. A metal oxide precursor comprising a metal suitable for use as a sulfur sorbent is dissolved in a second portion of deionized water, forming a metal salt solution. The metal salt solution and the sol mixture are mixed with a sol peptizing agent while heating and stirring, resulting in formation of a peptized sol mixture. The metal oxide precursor is dispersed substantially throughout the peptized sol mixture, which is then dried, forming a dry peptized sol mixture. The dry peptized sol mixture is then calcined and the resulting calcined material is then converted to particles.

Abstract: The present invention includes processes and resulting structures for producing moisture absorbing desiccant entrained polymers. A polymer is caused to assume a molten state, typically by applying heat and melting the polymer. To achieve certain results in the hardened end product, such as rigidity and durability, the polymer normally acts as a moisture barrier in a solidified state, both before and after melting. A desiccating agent is blended into the polymer so that the desiccating agent is distributed within the polymer. A channeling agent is also blended into the polymer so that it is distributed within the polymer. Together, the polymer, desiccating agent and channeling agent create a blended mixture. The mixture is solidified so that the channeling agent forms passages in the mixture through which moisture is communicable to desiccating agent that is entrained within the mixture. The solidified mixture may be used to form plug type inserts and liners for closed containers, or it may be used for producing laminated sheeting employed as package wrap.
