Effect of preparation method on halloysite supported cobalt catalysts for Fischer-Tropsch synthesis

Abstract

Novel cobalt Fischer-Tropsch synthesis (FTS) catalysts were prepared from natural halloysite nanotubes (HNT) by double-solvent and wet-impregnation methods, and characterized by TEM, XRD, TPR and N₂ adsorption-desorption. Comparing with the catalyst prepared by wet-impregnation method, the catalyst prepared by double-solvent method reduces Co₃O₄ particle migration and agglomeration due to size-induced effect, thus showing higher catalytic activity for Fischer-Tropsch synthesis.
