Title: McMahon L Gray: Innovator in Fly Ash Beneficiation
Introduction
McMahon L Gray is a notable inventor based in Pittsburgh, PA (US). He has made significant contributions to the field of materials science, particularly in the area of fly ash beneficiation. His innovative approach has the potential to enhance the recycling of industrial byproducts, thereby promoting sustainability.
Latest Patents
Gray holds a patent for a "Continuous air agglomeration method for high carbon fly ash beneficiation." This method effectively separates the carbon and mineral components of fly ash, resulting in a substantially carboree mineral stream and a highly concentrated carbon product. The process involves mixing fly ash with a liquid hydrocarbon to form a slurry, which is then treated with an aqueous solution. Through mechanical mixing and/or aeration, the hydrocarbon slurry is dispersed into small droplets, allowing for the concentration of inorganic mineral matter and the agglomeration of carbon and hydrocarbon droplets. The method culminates in the collection of these droplets, the separation of hydrocarbon from the concentrated carbon product, and the recycling of the hydrocarbon.
