| titleOfInvention | Manufacture of high-purity alumina and co-products from used electrolytes in metal-air batteries |
| abstract | Methods and systems are provided for converting used electrolytes from aluminium-air batteries into high-purity alumina (HPA) and useful co-products such as fertilizers and / or feed aids. For example, aluminum hydroxide (ATH) having potassium (K) and / or sodium (Na) impurities derived from a used electrolyte may be dissolved in a strong acid to form an acidic ATH solution having a pH <4. Subsequently, this acidic ATH solution may be neutralized to pH> 4, precipitating ATH and retaining the dissolved K / Na in the neutralized solution. The dissolution and neutralization may then be repeated with the precipitated ATH until a particular purity level of the precipitated ATH is reached. Use of suitable bases to neutralize acidic ATH solutions, such as ammonia and / or choline, will be useful co-productions such as ammonium nitrate (using nitric acid as a strong acid) and choline chloride (using hydrochloric acid as a strong acid), respectively. You get things. [Selection diagram] Fig. 1 |
