Latest Patents
Masaji Nakatani holds a patent for a process aimed at regenerating permanganate and/or manganate from manganese. The patent describes a method where NO.sub.x is absorbed in an alkaline aqueous solution of a permanganate and/or a manganate. The manganese compounds are reduced to form a precipitate of manganese dioxide. This manganese dioxide is then dispersed in an aqueous solution of sodium or potassium hydroxide with a concentration exceeding 20%. A gas containing NO.sub.x, with a molar ratio of NO.sub.2 /NO.sub.x greater than 0.55, is contacted with the dispersion in the presence of a permanganate and/or a manganate at temperatures above 40°C. This process effectively converts manganese dioxide back into permanganate and/or manganate.
