Annotation
This article discusses the possibilities of obtaining water-soluble liquid fertilizers enriched with microelements by acid processing of spent catalysts of the SHIFT MAX 210 brand, widely used in the nitrogen industry. Studies have been conducted on the effect of nitric acid concentration (in the range of 20–50%) on the degree of extraction of macro- and microelements. Physicochemical and rheological properties of the obtained solutions have been determined. The results demonstrate the prospects for developing an energy-efficient technology for processing catalyst waste using local raw materials, which is relevant in the environmental conditions of the Republic of Uzbekistan.
