Автор: Chett Boxley, Jessica Mckelvie

Принадлежит: Ceramatec Inc

An animal litter composition that includes geopolymerized ash particulates having a network of repeating aluminum-silicon units is described herein. Generally, the animal litter is made from a quantity of a pozzolanic ash mixed with an alkaline activator to initiate a geopolymerization reaction that forms geopolymerized ash. This geopolymerization reaction may occur within a pelletizer. After the geopolymerized ash is formed, it may be dried and sieved to a desired size. These geopolymerized ash particulates may be used to make a non-clumping or clumping animal litter or other absorbing material. Aluminum sulfate, clinoptilolite, silica gel, sodium alginate and mineral oil may be added as additional ingredients.

Functionalized magnetic particles are emerging as a reliable and convenient technique in the purification of biomacromolecules (proteins and nucleic acids). We disclose a novel coupling procedure that can be used to create stable ferromagnetic nickel particles coated with Protein A for the affinity purification of antibody. The protein purification procedure is gentle, scalable, automatable, efficient and economical. By modifying the functional groups of amino acids in the protein coating, nickel particles can be used not only for affinity purification but for other sample preparation and chromatographic applications as well including nucleic acid isolations. The method can be easily modified for small and medium scale antibody purification in lab and pre-clinical research.

A sorbent composition for enhanced baghouse function is described. The composition may include a sorbent such as powder activated carbon as well as an additive that is a heat moderator or a permeability agent. The heat moderator may act as a heat sink or barrier. Heat moderators may include in non-limiting examples phyllosilicates, cyclosilicates, or nesosilicates that may include, montmorillonite, bentonite, halloysite, aluminum silicates, muscovite, illite, kaolin, andalusite, kyanite, sillimanite, metakaolin, mullite, polymers, such as chitosan, and/or clays, either natural or synthetic (e.g., montmorillonite), or polyethylenimine. Permeability may be affected by mixing sorbents of lower D50 with sorbents of higher D50 in various ratios, or addition of a permeability agent such as a phyllosilicate, perlite, silica, diatomaceous earth. Further, a permeability agent such as a fluoropolymer may be coated onto or admixed with the sorbent. Diatomaceous earth, perlites, or silicates may also increase permeability. The compositions are particularly useful in flue gas treatment systems with baghouse separation units in that they have reduced combustibility and increased permeability properties. 1. A method for the treatment of a flue gas stream to remove contaminants therefrom , comprising the steps of:burning a combustible material, the burning creating a flue gas stream containing contaminants;contacting the flue gas stream with a sorbent composition to sequester the contaminants from the flue gas stream; andcapturing the sorbent composition in a baghouse unit,wherein the sorbent composition comprises a sorbent having a median particle diameter (D50) of not greater than about 30 μm and at least a first heat moderator.2. The method recited in claim 1 , wherein the first heat moderator is selected from the group consisting of phyllosilicates claim 1 , cyclosilicates claim 1 , nesosilicates claim 1 , colloidal silicates claim 1 , aluminum silicates claim 1 , mullite claim ...
