Document Type and Number:
WIPO Patent Application WO/2007/113962
Kind Code:
A1
Abstract:
A method of hydrotreating a wax, characterized by comprising: a step in which
a wax produced by FT synthesis is used as a raw material and the wax is hydrocracked
in the presence of hydrogen with a catalyst comprising a support comprising zeolite
and, deposited thereon, a metal in Group VIII of the Periodic Table; a step in which
the raw material is temporarily switched from the wax to a distillate oil obtained
by distillating a mixture of the product of wax hydrocracking obtained in the
first step and the product of hydrocracking of an intermediate fraction produced
by FT synthesis, and the distillate oil is hydrocracked in the presence of hydrogen
at a reaction temperature of 160-330°C; and a step in which the raw material
is switched from the distillate oil to the wax and the wax is hydrocracked in the
presence of hydrogen.
