    摘要： The hydrocracking method of wax of the invention is a hydrocracking process wherein crude wax is subjected to hydrocracking and the untreated wax fraction that is produced after the hydrocracking is re-supplied for hydrocracking, and wherein hydrocracking of the mixture of the crude wax and untreated wax fraction is carried out in such a manner for a conversion ratio of 50-85% by mass from the wax fraction with a boiling point of 360° C. or above to the light fraction with a boiling point of below 360° C. in the presence of a hydrocracking catalyst. It is thereby possible to simultaneously achieve both an increased heart-cut fraction yield (as the product of the hydrocracking) and a reduced normal paraffin content in the heart-cut fraction when the untreated wax is hydrocracked by a bottom recycling system.
