English Abstract

Process for producing a hydrowax comprising the steps
of
(a) hydrocracking a blend obtained by blending at least
one distillate fraction and a deasphalted oil (DAO);
(b) separating from the hydrocracker effluent a fraction
of which at least 90% by weight has a boiling point of
370 °C or higher (the 370+ fraction); and
(c) separating the 370+ fraction in a top-fraction and a
bottom-fraction at an effective cutpoint below 600 °C,
thus yielding the hydrowax as the top-fraction.
The hydrowax thus produced is a very suitable
feedstock for a steam cracker for the production of
ethene. The hydrowax can also be very suitably applied as
a feed for the production of lubricating base oils.
