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

摘要

Novel cobalt Fischer-Tropsch synthesis(FTS) catalysts were prepared from natural halloysite nanotubes(HNT) by double-solvent and wetimpregnation methods,and characterized by TEM,XRD,TPR and N2 adsorption-desorption.Comparing with the catalyst prepared by wetimpregnation 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.
