Patent number: 11633713Abstract: This disclosure relates to ultra-high performance diatomite products possessing very high silica specific volume, a characteristic which provides for high filtration performance, in terms of low unit consumption and long filtration cycle times. These novel products of this disclosure also show very low extractable metals for both the non-acid washed and the high purity (acid washed) grades. These characteristics are of particular value in the separation of solids from high purity liquids in electronic chemical, specialty beverage and life science applications. In addition to outstanding physical and chemical characteristics, these products also contain no detectable levels of cristobalite and have a wide range of permeabilities, and are produced from mineralogically impure ores containing high levels of alumina and iron oxide.Type: GrantFiled: January 6, 2017Date of Patent: April 25, 2023Assignee: EP Minerals, LLCInventors: Scott Kevin Palm, George A. Nyamekye

Publication number: 20230032214Abstract: A product, a method of producing and a method of using are disclosed. The product comprises attapulgite that has been thermally activated. The product may have a permeability in oil in the range of 0.04-3 darcy and may have a surface area of 45-140 m2/g. The method of producing may comprise thermally activating a material that includes attapulgite by heating the material at a temperature in the range of 300 to 900° C. The method of decolorizing may include contacting for a contact time an oil with the bleaching clay product that comprises attapulgite that has been thermally activated, and separating the bleaching clay product from the oil to recover a decolorized oil that has a lower red color than the oil had prior to the contacting, and removing phosphorus and metals for hydrotreated vegetable oil (HVO)/renewable diesel feedstock pretreatment.Type: ApplicationFiled: June 30, 2022Publication date: February 2, 2023Applicant: Active Minerals International, LLCInventors: Bo WANG, Scott Kevin PALM, Dennis PARKER

Patent number: 11565940Abstract: This disclosure concerns flux-calcined products manufactured from filtration waste streams, and methods for manufacturing the same. In particular, it concerns functional additives produced from spent cake comprising diatomite filtration media which are suitable for use in paints, plastic films and elastomers for control of optical and surface properties, and processes which are suitable for manufacture of such products. It further concerns the recovery of energy from spent cakes during the regeneration process.Type: GrantFiled: August 4, 2017Date of Patent: January 31, 2023Assignee: EP Minerals, LLCInventors: Scott Kevin Palm, Peter E. Lenz, Andrew R. Welford, George A. Nyamekye, Kara Linn Evanoff

Patent number: 11511220Abstract: This invention concerns ultra-high purity, ultra-high performance biogenic silica filtration products comprising diatomaceous earth. In particular, it relates to products comprising diatomaceous earth which is derived from ores that have been specifically selected for their naturally low centrifuged wet density and which have been intensively beneficiated to reduce extractable impurities to near or below detection limits. The low centrifuged wet density of the selected natural ore is either maintained or further reduced through the beneficiation process, which provides for filtration product/media with high particulate holding capacities able to provide for extended filtration cycle times.Type: GrantFiled: January 6, 2017Date of Patent: November 29, 2022Assignee: EP Minerals LLCInventors: George A. Nyamekye, Scott Kevin Palm, Peter E. Lenz, Qun Wang

Publication number: 20220048009Abstract: This invention concerns highly effective functional additive products that comprise diatomite. More particularly, it concerns such functional additive products possessing particle size distributions which make them more effective as functional additives in filled systems. Higher effectiveness is demonstrated through lower Standard Sheen and/or reduced unit consumption relative to diatomite functional additives already in the public domain. Such products may also possess high brightness, low tint and/or an absence of detectable crystalline silica.Type: ApplicationFiled: December 20, 2018Publication date: February 17, 2022Applicant: EP MINERALS, LLCInventors: Scott Kevin PALM, Fangfu ZHANG
