Abstract

Integrated hydroprocessing methods using high activity, low density catalysts are provided. The high activity catalysts allow for lower temperature operation, which reduces catalyst degradation, while the low density of the catalysts means a corresponding reduction in the amount of metal needed to fill a reactor volume. The methods allow for flexible processing of feedstocks with a variety of wax contents.
