Title:
METHOD OF WAX HYDROCRACKING
Document Type and Number:
WIPO Patent Application WO/2007/102397
Kind Code:
A1
Abstract:
A method of wax hydrocracking, characterized by disposing in a fixed-bed reactor
a first hydrocracking catalyst layer and a second hydrocracking catalyst layer
respectively on the upstream side and downstream side in the reactor so as to satisfy
the requirement represented by the following relationship (1), passing hydrogen
and a wax through the first hydrocracking catalyst layer, additionally adding
hydrogen to a decomposition product from the first hydrocracking catalyst layer
upstream from the upstream end of the second hydrocracking catalyst layer, and
passing a mixture comprising the decomposition product and the hydrogen additionally
added through the second hydrocracking catalyst layer. d1/(d1+d2)≥1/3
(1) [In the relationship (1), d1 indicates the distance between the
upstream end and downstream end of the first hydrocracking catalyst layer; and
d2 indicates the distance between the upstream end and downstream
end of the second hydrocracking catalyst layer.]
