Study of the Stability of Catalysts for Decomposition of Spent Sulfuric Acid

Abstract

The influence of various factors on the stability of operation of heterogeneous catalysts for decomposition of spent sulfuric acid is analyzed.The stability of operation of a catalyst [1] in decomposition of spent sulfuric acid (SSA) containing organic admixtures is strongly affected by several factors, including the mechanical action associated with the mode of the boiling bed and a long exposure to a high temperature. The first factor can promote destruction of the support and removal of active components. The second can diminish the catalytic activity through a transformation of the porous structure that leads to a decrease in the specific surface area. This study is devoted to examination and analysis of the effect of these factors on the catalyst.
