Abstract
A method for thermally decomposing manganese nitrate in an aqueous solution containing alkali and/or alkaline earth nitrates including splashing said aqueous solution containing manganese nitrate to form droplets or sheets of solution, heating said droplets or sheets of solution to partially decompose each droplet or sheet of solution to form manganese dioxide and nitrogen dioxide, and reuniting said droplets or sheets of solution containing manganese dioxide with said aqueous solution containing manganese nitrate; and/or spraying said aqueous solution containing manganese nitrate to form droplets of solution, heating said droplets of solution to fully decompose each droplet to form nonstoichiometric manganese dioxide, and nitrogen dioxide, and recovering said nonstoichiometric manganese dioxide.
Claims4
A method for decomposing manganese nitrate in an aqueous solution containing alkali and/or alkaline earth nitrates, comprising the steps of:
- (a) spraying said aqueous nitrate solution containing about 0.5 to 0.8 grams of soluble manganese per gram of total alkali and/or alkaline earth compounds to form droplets of solution,
- (b) heating said droplets of solution to fully decompose each droplet to form a fluid product slurry containing nonstoichiometric manganese dioxide, nitrogen dioxide and water vapor, and
- (c) recovering said fluid product slurry containing nonstoichiometric manganese dioxide.
