Preparation method of high performance iron/alumina catalysts and manufacturing method of synthetic liquid fuel using the iron/alumina catalyst
Preparation method of high performance iron/alumina catalysts and manufacturing method of synthetic liquid fuel using the iron/alumina catalyst
The present invention relates to an iron/potassium/alumina composite catalyst for a Fischer-Tropsch synthesis reaction capable of obtaining a synthetic liquid fuel from a mixed gas containing carbon monoxide and hydrogen, and a manufacturing method and use thereof. The catalyst manufacturing method according to the present invention is a melt-infiltration of hydrated iron hydrate salt in the pores of the alumina support so that the content of the supported iron salt is 0.4 to 1 gram (g) per unit gram (g) of the alumina support. The first step; And a second step of activating the ferrous metal hydrate supported in the pores of the alumina support with iron carbide by firing in an atmosphere of an activation gas to form a porous ferric carbide/alumina catalyst in which the iron carbide nanoparticles are supported in the pores of the alumina support. It is a feature.
