Latest Patents

One of Dieter A Knecht's latest patents involves the development of a method for the removal of radioactive and other hazardous materials from fluid waste. This innovative approach utilizes hollow glass microspheres, specifically cenospheres obtained from fly ash, which are impregnated with extractants or ion-exchangers. In one embodiment, these microspheres are loaded with ammonium molybdophosphonate (AMP) to extract radioactive ions such as cesium-137 from acidic liquid wastes. Another embodiment uses octyl(phenyl)-N-N-diisobutyl-carbamoylmethylphosphine oxide (CMPO) for the removal of americium and plutonium from similar waste types.

Additionally, Knecht has developed an open-cell glass crystalline porous material made from these hollow microspheres, exhibiting an incredible open-cell porosity of up to 90 vol.%. The production process involves separating the cenospheres into fractions according to grain size, density, and other characteristics before molding and agglomerating the selected fractions at controlled temperatures. This porous material has significant properties that make it useful as matrices for immobilizing liquid radioactive waste, filters, and catalyst supports.
