    摘要: A process has been developed for preparing a Fischer-Tropsch catalyst precursor and a Fischer-Tropsch catalyst made from the precursor. The process includes contacting a gamma alumina catalyst support material with a first solution containing a compound containing zinc and optionally containing P, Ti, V, Co, Ga, Ge, Mo, W and/or Pr to obtain a modified catalyst support material. The modified catalyst support material is calcined at a temperature of at least 500° C. The calcined modified catalyst support has a pore volume of at least 0.4 cc/g. The modified catalyst support is less soluble in acid solutions than an equivalent unmodified catalyst support. The modified catalyst support is contacted with a second solution which includes a precursor compound of an active cobalt catalyst component to obtain a catalyst precursor. The catalyst precursor is reduced to activate the catalyst precursor to obtain the Fischer-Tropsch catalyst. The catalyst has enhanced hydrothermal stability as measured by losing no more than 20% of its pore volume when exposed to water vapor.
