    • The invention pertains to a process for preparing spherical oxide particles comprising the steps of shaping a starting material comprising an oxide hydrate into particles of substantially constant length by leading the material to a set of two rolls rotating towards each other followed by leading the material to a roll equipped with grooves to form rod-type shapes, cutting the rod-type shapes into particles of substantially constant length, converting the thus formed particles into spheres, and heating the particles to convert the oxide hydrate into an oxide. The process results in particles in which there is substantially no difference in density between the core portion and the shell portion of the particles, which results in a high abrasion resistance. The particles prepared by the claimed process are particularly suitable for the preparation of hydroprocessing catalysts, more in particular for the preparation of hydroprocessing catalysts suitable for the hydroprocessing of heavy hydrocarbon feeds.
    • 本发明涉及一种制备球形氧化物颗粒的方法,包括以下步骤:将包含氧化物水合物的起始材料成形为具有基本上恒定长度的颗粒,通过将材料引导到彼此相对转动的一组两个辊,然后将材料引导到 辊装配有沟槽以形成杆状形状,将棒状形状切割成基本恒定长度的颗粒,将如此形成的颗粒转化成球体,并加热颗粒以将氧化物水合物转化为氧化物。 该过程产生颗粒的核心部分和壳体部分之间的密度基本上没有差异的颗粒,这导致高耐磨性。 通过所要求保护的方法制备的颗粒特别适用于制备加氢处理催化剂,特别适用于制备适用于加氢处理重质烃进料的加氢催化剂。
