Mesoporous palladium-alumina catalyst for mild hydrocracking, preparation method thereof, and method for producing middle distillate through hybrid Fischer-Tropsch synthesis using said catalyst

摘要

PURPOSE: A porous palladium-alumina catalyst for hybrid Fischer - Tropsch synthesis, a manufacturing method thereof, a continuous flow double reaction device, and a manufacturing method of middle distillate using the same are provided to increase dispersion of palladium compared to the other catalyst. CONSTITUTION: A manufacturing method of a porous palladium - alumina catalyst for hybrid Fischer - Tropsch synthesis includes the following steps: manufacturing an aluminum - palladium precursor mixed solution by mixing palladium precursor alcohol in a mixed solution of an aluminum precursor alcohol solution and an anionic micelle alcohol solution; manufacturing slurry by maintaining a temperature of the aluminum - palladium precursor mixed solution at 80 ~ 120 C; drying and washing the aluminum - palladium precursor mixed solution; and sintering the dried aluminum palladium precursor slurry at a temperature of 500 ~ 1000 C.
