Abstract

A review of the scientific and technical literature on hydrometallurgical methods for extracting high-purity vanadium oxide from spent catalysts in the petrochemical industry has been carried out. Currently, high-purity vanadium oxide (V 2 O 5 ≥ 99.5%) is not produced in Russia. The main consumer of high-purity vanadium oxide is the rapidly developing production of vanadium-containing master alloys for the manufacture of titanium alloys. In the chemical industry, high-purity vanadium oxide is used to produce catalysts for the synthesis of phthalic and maleic anhydrides. One of the promising sources of vanadium is spent (deactivated) vanadium catalysts (SVC), in which the content of the valuable component in terms of pentoxide (V 2 O 5 ) can reach 4–8%. It is much higher than in most processed ore raw materials. Spent catalysts are a secondary raw material, since during opera-tion there is a loss of catalytic properties (activity, conversion, selectivity). After several cycles of regene-ration, such a product is a subject of recycling to obtain valuable components. It should also be noted that there is an increase in demand for hydrotreating catalysts, which may cause an excess of spent catalysts in the future. In this regard, there is an urgent need to develop a highly efficient technology for processing catalysts in order to extract valuable components. The review of the scientific and technical literature shows that there are many methods for processing spent catalysts. The article describes the methods of acid, alkali, soda leaching, as well as the perfor-mance indicators of these processes. But the existing scientific developments in this area need further development in order to improve the efficiency of the vanadium oxide leaching process. DOI: 10.17580/nfm.2022.01.04

石油化工催化剂中氧化钒提取的现代科学进展综述

对石油化工用废催化剂湿法提取高纯氧化钒的科技文献进行了综述。目前，俄罗斯不生产高纯氧化钒(v2o5≥99.5%)。高纯氧化钒的主要消费者是快速发展的钛合金用含钒母合金生产。在化学工业中，高纯氧化钒用于生产合成邻苯二甲酸酐和马来酸酐的催化剂。废(失活)钒催化剂(SVC)是一种很有前途的钒源，其中以五氧化二钒(v2o5)为单位的有价组分含量可达4-8%。它比大多数加工过的矿石原料要高得多。废催化剂是二级原料，因为在操作过程中，催化性能(活性、转化率、选择性)会损失。这样的产品经过几次循环再生后，是回收的对象，以获得有价值的成分。还应该指出的是，对加氢处理催化剂的需求有所增加，这可能会导致未来使用的催化剂过剩。在这方面，迫切需要开发一种高效的催化剂处理技术，以提取有价值的成分。对科技文献的回顾表明，处理废催化剂的方法多种多样。本文介绍了酸浸、碱浸、碱浸的方法，以及这些工艺的性能指标。但为了提高氧化钒浸出工艺的效率，现有的科学进展还需要进一步发展。DOI: 10.17580 / nfm.2022.01.04
