Latest Patents
One of his latest patents focuses on the hydrothermal carbonization of sewage wastes. This method provides a way to treat sewage wastes to obtain valuable products, including fatty acids, carbon-neutral combustible hydrochar fuels, heavy metal salts for recycling into industrially important metals, and phosphoric acid and its derivatives. The fatty acids can be transformed into useful products such as soaps, cosmetics, and liquid transportation fuels like biodiesel and conventional gasoline. The hydrochars produced can be combusted to generate electricity, while heavy metal salts can be reduced to form important metals for use as catalysts. Additionally, phosphoric acid plays a crucial role as a fertilizer in agriculture.
Another significant patent involves methods for producing coal and fertilizers from fermentation residues. This process allows for the creation of synthetic coal and aqueous liquid plant fertilizing solutions from the residues left over from corn-based ethanol production. The synthetic coal has a high heat value and lower ash and sulfur content, making it a clean-burning energy source. The aqueous fertilizer contains commercially useful amounts of phosphorous, potassium, and nitrogen, and the process is energy efficient compared to traditional methods.
