摘要

The present invention relates to a cobalt-based catalyst on the basis of a metal structure for a Fischer-Tropsch reaction for manufacturing selective synthetic oil, a manufacturing method thereof, and a method for manufacturing selective synthetic oil using the cobalt-based catalyst on the basis of the metal structure. The purpose of the present invention is to provide: the cobalt-based catalyst on the basis of the metal structure, capable of thinly and uniformly coating a catalytic sol pulverized after mixing zeolite, cobalt and a support on the surface of the metal structure so as to prevent heating during the Fischer-Tropsch reaction, and, at the same time, to allow selective production of the synthetic oil having carbon chains shorter than a wax region using a spray coating method; the manufacturing method thereof; and the method for manufacturing selective synthetic oil. The present invention is characterized by inventing a method for manufacturing the cobalt-based catalyst on the basis of the metal structure for a Fischer-Tropsch reaction for manufacturing selective synthetic oil, the catalyst thereof, and the synthetic oil manufactured the same, wherein the method comprises the steps of: manufacturing cobalt-oxide/metal-oxide support catalyst powder by burning mixed powder obtained through melting and impregnation between cobalt hydrate salt and a metal-oxide support; manufacturing hybrid catalyst powder by mixing the cobalt-oxide/metal-oxide support catalyst powder and zeolite powder; manufacturing a hybrid catalyst sol through pulverization after mixing the hybrid catalyst powder with an organic binder and an inorganic binder; coating the metal structure the surface of which is treated with alumina through the ALD process by spraying the hybrid catalyst sol; and performing a heat treatment on the metal structure on which the hybrid catalyst sol is sprayed.
