Abstract: Systems and methods are provided for activation of noble metal catalysts that are supported on siliceous supports. The activation method can include limiting the amount of water vapor pressure and/or the time of exposure to the water vapor pressure during heating of the catalyst at temperatures of 50° C. or less. This can be achieved by introducing heated gas into multiple reactors of a multi-reactor system at the same time. A suitable system for introducing heated gas into multiple reactors can correspond to a system with multiple heated hydrogen lines for delivery of heated hydrogen to a plurality of reactors within a multi-reactor system.

Abstract: A process for producing high yields of higher quality (API Group II, Group III′) lubricating oil basestock fractions which allows the production of two or more types of high quality lubes in continuous mode (no blocked operation mode) without transition times and feed or intermediate product tankage segregation. Two consecutive hydroprocessing steps are used: the first step processes a wide cut feed at a severity needed to match heavy oil lube properties. The second step hydroprocesses a light oil after fractionation of the liquid product from the first step at a severity higher than for the heavy oil fraction. The two hydroprocessing steps will normally be carried out in separate reactors but they may be combined in a single reactor which allows for the two fractions to be processed with different degrees of severity.

Abstract translation: 生产高产量的高质量（API Group II，Group III'）润滑油基础油馏分的方法，其允许以连续模式（无阻塞操作模式）生产两种或更多种类型的高质量润滑剂，而不需要过渡时间和进料或 中间产品油罐分离。 使用两个连续的加氢处理步骤：第一步按照重油润滑油性能所需的严重程度处理宽切削进料。 第二步骤是以比重油馏分高的浓度从第一步骤中分离液体产物之后加氢轻质油。 两个加氢处理步骤通常在单独的反应器中进行，但是它们可以在单个反应器中组合，这允许以不同的严重程度处理两个馏分。
