Document Type and Number:
WIPO Patent Application WO/2007/097235
Kind Code:
A1
Abstract:
A process for hydrocracking wax which comprises hydrocracking a raw material
wax and subjecting an uncracked wax fraction formed by the hydrocracking to hydrocracking
again, characterized in that a mixture of the raw material wax and the uncracked
wax fraction is hydrocracked in the presence of a hydrocracking catalyst in such
a way that the conversion of the wax fraction having a boiling point of 360°C
or above into a light oil fraction having a boiling point lower than 360°C
falls within the range of 50 to 85% by mass. In hydrocracking uncracked wax by a
bottom recycling method, the process simultaneously attains enhancement in
the yield of objective middle cuts and reduction in the content of n-paraffins
in middle cuts.
