Title: John E Deutschman: Innovator in Aluminium Reduction Technology
Introduction
John E Deutschman is a notable inventor based in Kingston, CA, recognized for his contributions to the field of aluminium reduction technology. With a total of 4 patents to his name, Deutschman has developed innovative processes that address environmental challenges associated with aluminium production.
Latest Patents
One of Deutschman's latest patents focuses on the treatment of scrap lining material from aluminium reduction cells. This process involves mixing fluoride-contaminated scrap lining material with 7-30 parts of sulphuric acid and sufficient water to achieve a liquid content of 60-80 parts per 100 parts of lining material. The mixture is then combined with lime to neutralize the sulphuric acid, resulting in a slurry that is allowed to set into a solid mass. The slurry should maintain a paste-like consistency, and the scrap material is preferably heated to 150-500 degrees Celsius in the presence of water vapor to eliminate cyanides.
Another significant patent pertains to the recovery of alumina values from a starting solid mixture. This process involves mixing a solid mixture of AlCl3 and NaCl with water to form an aqueous solution. The solution is then sparged with HCl to precipitate AlCl3, ensuring that the sparging is halted before a substantial concentration of NaCl begins to emerge from the solution. The precipitated AlCl3 can be calcined to produce Al2O3 and washed to remove any residual NaCl.
