HYDROCRACKING METHOD, HYDROCRACKED OIL PRODUCTION METHOD, HYDROCRACKING APPARATUS, AND HYDROCRACKED OIL PRODUCTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a hydrocracking method excellent in treatment cost by increasing the catalytic activity of an iron-based catalyst during reuse, a hydrocracked oil production method using the hydrocracking method, a hydrocracking apparatus, and a hydrocracked oil production apparatus with the hydrocracking apparatus.;SOLUTION: A hydrocracking method of petroleum heavy oil containing heavy metal components according to the present invention includes the steps of: supplying raw material slurry comprising the petroleum heavy oil and an iron-based catalyst and hydrogen gas to a hydrocracking reactor; hydrocracking the petroleum heavy oil in the hydrocracking reactor; recovering a residual oil component containing the iron-based catalyst from a product after the hydrocracking step; cracking the iron-based catalyst in the recovered residual oil component; and resupplying the treated residual oil component containing the cracked iron-based catalyst to the hydrocracking reactor. The iron-based catalyst is preferably pulverized by a pulverizer in the cracking step. The iron-based catalyst is preferably limonite.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
