摘要： The present invention relates to a method of unloading a catalyst from a reactor wherein the reactor is filled with mixed liquid of condensed ring aromatic hydrocarbon having a required number of ring members, i.e. preferably 2 to 4 ring members, and gas oil, to wet the catalyst so as to form a coating of film on the catalyst before unloading the catalyst from the reactor.

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.
