摘要：
A method of removing a catalyst used for catalytic reactions of hydrocarbons from a reaction system for exchange or otherwise comprising treating the catalyst with water or a mineral oil in the presence of a surface active substance or both a surface active substance and a chelating agent to wet the catalyst. This method ensures a safe and simple removal of the catalyst without involving dust scattering, spontaneous combustion or generation of sulfur dioxide gas.
