Introduction
David Bridson Oates is a notable inventor based in Kettleby, Ontario, Canada, with a remarkable portfolio of ten patents. His innovative work primarily focuses on enhancing industrial processes that contribute to environmental sustainability and the advancement of materials used in construction.
Latest Patents
One of Oates' latest patents involves the use of organic carbon-containing minerals. In this invention, a synthetic slag is created by melting the mineral content of organic carbon materials, such as oil shale or tar sands, together with a source of lime like cement kiln dust. During the process, the organic carbon, particularly hydrocarbons, is oxidized in an exothermic reaction using oxygen gas. The heat generated in this reaction facilitates the interaction between the mineral content and lime. The gaseous outputs typically include nitrogen, unreacted oxygen, water vapor, and carbon dioxide, while heat energy can be effectively recovered from the resulting hot off-gas products. Additionally, this synthetic slag can be pelletized or milled to provide lightweight mineral aggregates or fine slag cement.
Another recent patent addresses carbon removal through partial carbon burn-out from coal ash used in concrete. The durability of concrete against freeze-thaw cycles largely depends on its air entrainment level, which is maintained through surface-active agents. These agents fragment large air voids into smaller ones, stabilizing the air in the concrete. However, fly ash, when used as a pozzolanic component, can adsorb these air-entraining agents, thereby reducing the concrete's durability. Oates' invention describes a technique for the partial removal of carbon from coal ash via controlled combustion of its fine carbon fraction, which ensures the improvement of freeze-thaw properties in concrete.
