Abstract

Integrated hydroprocessing methods using high activity, low density catalysts are provided. The high activity catalysts allow for blocked operation when processing lube range feedstocks of widely varying characteristics, such as wax content, without having to substantially change the configuration or operating conditions of the process train. Instead, the different feedstocks can be accommodated by varying the reaction temperature in the process train.
