Comparative Analysis of the Efficiency of Molybdenum Trioxide Extraction from a Spent Hydraulic Catalyst

Abstract

This work is a continuation of the search for optimal conditions for the selective extraction of molybdenum from spent molybdenum-containing hydrotreating catalysts. The optimal conditions for extracting molybdenum from molybdenum (VI) oxide MoO3 are determined. The kinetic regularities of the interaction of solutions of nitric acid (HNO₃) and sodium carbonate (Na₂CO₃) with a molybdenum-containing catalyst were described.
