Title:

PROCESS TO PREPARE A MICROCRYSTALLINE WAX AND A MIDDLE DISTILLATE FUEL

Document Type and Number:

WIPO Patent Application WO2004009739

Kind Code:

A3

Abstract:

Process to prepare a microcrystalline wax and a middle distillate fuel by (a) hydrocracking/hydroisomerisating a Fischer-Tropsch product, wherein weight ratio of compounds having at least 60 or more carbon atoms and compounds having at least 30 carbon atoms in the Fischer-Tropsch product is at least 0.2 and wherein at least 30 wt% of compounds in the Fischer-Tropsch product have at least 30 carbon atoms, (b) performing one or more distillate separations on the effluent of step (a) to obtain a middle distillate fuel fraction and a microcrystalline wax having an initial boiling point of between 500 and 600 °C.
