METHOD FOR WITHDRAWING SOLID CATALYST AND REACTION EQUIPMENT FOR SOLID CATALYST |
摘要 |
PROBLEM TO BE SOLVED: To provide a method for shortening the working time when a solid catalyst packed in a reactor is withdrawn and improving the working environment satisfactorily and to provide reaction equipment for solid catalyst from the reactor of which the solid catalyst can be withdrawn easily. SOLUTION: This method for withdrawing the solid catalyst packed in the reactor comprises steps of introducing a low-viscosity liquid into the reactor and withdrawing the solid catalyst together with the introduced low-viscosity liquid. When the solid catalyst packed in the reactor is an ion exchange resin, this method produces a particularly satisfactory result. This reaction equipment 10 for solid catalyst is provided with: the reactor 12 packed with the solid catalyst 11; a low-viscosity liquid introducing pipeline 13 for introducing the low-viscosity liquid into the reactor 12; and a solid catalyst discharging pipeline 14 for discharging the solid catalyst 11 from the reactor 12.
