Two-catalyst hydrocracking process |
| abstract |
The process comprises contacting a feedstock which boils above about 350*F. and which contains nitrogen in an amount within the range of about 1 ppm to about 3,000 ppm in a feed-preparation zone in the presence of hydrogen and under hydrodenitrogenation conditions with a hydrodenitrogenation catalyst to obtain a denitrogenated effluent, and contacting at least a portion of the denitrogenated effluent in a hydrocracking zone in the presence of hydrogen and under hydrocracking conditions with a hydrocracking catalyst to obtain a hydrocracked effluent. The hydrodenitrogenation catalyst comprises as a hydrogenation component a Group VIA metal and Group VIII metal and/or their compounds and a cocatalytic acidic support comprising a largepore crystalline aluminosilicate material and a refractory inorganic oxide. The hydrocracking catalyst comprises as a hydrogenation component a Group VIA metal and a Group VIII metal and/or their compounds, and an acidic support of large-pore crystalline aluminosilicate material. For both hydrodenitrogenation catalyst and the hydrocracking catalyst, the preferred hydrogenation component comprises nickel and tungsten and/or their compounds and the preferred large-pore crystalline aluminosilicate material is ultrastable, large-pore crystalline aluminosilicate material. The preferred process is a single-stage process. |
