The novel method to load Zr on SiO2 support (LPD method) was developed for the preparation of Fischer-Tropsch catalysts. For the LPD method, when the amount of Zr increased, the decreasing of BET surface area of catalyst was very small compared with the Incipient Wetness (IW) method. This suggested that for the LPD method Zr was loaded in the form of thin film on SiO2 support. In the catalyst evaluation with a flow reactor, the catalyst prepared by the LPD method showed higher catalytic activity than the catalyst prepared by the IW method. To understand such a high activity, the Zr distribution of catalysts was measured with EPMA. It was observed that Zr loaded by the LPD method was localized on the external surface of catalyst, which could contribute to give a high activity as a promoter.
