A distillate fuel feed is hydrotreated to remove heteroatoms and then
separated into light and heavy hydrotreated fractions, with the heavy
fraction catalytically dewaxed to improve low temperature properties. The
hydrotreating and dewaxing are conducted in separate stages, which may be
in the same reactor vessel. Fresh hydrogen may be passed into the
dewaxing stage, with the dewaxing stage gaseous effluent then passed into
the hydrotreating stage to provide hydrogen for the hydrotreating.
Existing hydrotreating reaction vessels and facilities may be retrofitted
to add one or more dewaxing stages.
