摘要：
Zinc was introduced into gamma-Al2O3 by either co-precipitation or impregnation methods. Zinc introduced by co-precipitation was homogeneously dispersed in the framework of the support, while it was aggregated on the surface of alumina upon addition via impregnation. The co-precipitated prepared Zn-Al2O3 supported cobalt catalyst possessed appropriate pore structure, lower cobalt-support interaction and improved cobalt reducibility, thus showing a significantly enhanced catalytic activity with good stability in Fischer-Tropsch synthesis.
