    • A process is disclosed for preparing a Fischer-Tropsch catalyst precursor and a catalyst made from the precursor. The process includes contacting an alumina catalyst support material with a first solution containing a vanadium compound and a phosphorus compound, 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 and glutaric acid 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 and good activity.
    • 公开了制备费 - 托催化剂前体和由前体制备的催化剂的方法。 该方法包括使氧化铝催化剂载体材料与含有钒化合物和磷化合物的第一溶液接触,以获得改性的催化剂载体材料。 改性的催化剂载体材料在至少500℃的温度下煅烧。煅烧的改性催化剂载体的孔体积至少为0.4cc / g。 改性的催化剂载体在酸溶液中比相当的未改性的催化剂载体更难溶解。 改性的催化剂载体与包含活性钴催化剂组分的前体化合物和戊二酸的第二溶液接触以获得催化剂前体。 催化剂前体被还原以活化催化剂前体以获得费 - 托催化剂。 该催化剂具有增强的水热稳定性和良好的活性。
