    • An improved catalyst for the production of lube oil blending components, and lube oils, from waxy, paraffinic feeds, a process for producing such catalyst, and a process utilizing this catalyst in the production of lubes. The catalyst is a unitized mixed powder pellet catalyst constituted of a dehydrogenation component, or components, suitably a catalytically active Group VIB, VIIB, or VIII metal, or metals, an isomerization component, suitably an amorphous acidic solid support, and a small pore molecular sieve dewaxing component. The dewaxing component is characterized as a small pore molecular sieve wherein the pore windows are formed by 8 oxide atoms which form the limiting edge of the pore window, each of the oxide atoms constituting one of the four oxide atoms of a tetrahedrally coordinated cluster around a silicon or aluminum framework ion, or atom, each oxide ion is coordinated to two framework ions in these structures, and the pore size of the sieve ranges between about 6.3 .ANG. and 2.3 .ANG.. In preparation of the catalysts, the isomerization component, or the dewaxing component, or both, may provide the dehydrogenation function due to the presence of a catalytic metal, or metals, deposited thereon, in which case the components are powdered, the powders mixed together, compressed and formed into solids catalyst shapes comprised of these components. Alternatively, the dehydrogenation function can be added to preformed solids shapes made from powdered dewaxing and isomerization components.
    • 用于生产来自蜡质,石蜡原料的润滑油混合组分和润滑油的改进的催化剂,用于生产这种催化剂的方法,以及利用该催化剂生产润滑剂的方法。 催化剂是由脱氢组分或适当的催化活性组VIB,VIIB或VIII金属或金属,异构化组分,合适地为无定形酸性固体载体和小孔分子的组分组成的混合粉末颗粒催化剂 筛脱蜡组分。 脱蜡组分的特征在于小孔分子筛,其中孔窗由形成孔窗的限制边缘的8个氧化物原子形成,每个氧化物原子构成四面体配位簇的四个氧化物原子之一 硅或铝框架离子或原子,在这些结构中,每个氧化物离子与两个骨架离子配位,并且筛孔的孔径范围在约6.3安格姆和2.3安培之间。 在催化剂的制备中,异构化组分或脱蜡组分或两者均可以提供脱氢功能,因为沉积在其上的催化金属或金属的存在,在这种情况下,组分被粉碎,粉末混合在一起 ,压缩并形成由这些组分组成的固体催化剂形状。 或者,可以将脱氢功能加入由粉末状脱蜡和异构化组分制成的预制固体形状。
