Abstract
A noble metal hydrocracking catalyst which has high selectivity for naphtha range products is provided. The hydrocracking catalyst comprises: PA1 a) from about 70 to about 90 weight percent of a Y zeolite, based on the catalyst having a silica to alumina mole ratio of from about 4.8 to less than 6.0, a unit cell constant within the range of about 24.50 to about 24.57, a Na.sub.2 O level of less than or equal to about 0.2 weight percent; PA1 b) from about 10 to about 30 weight percent, based on the catalyst of an alumina having a mercury intrusion pore volume within the range from about 0.55 to about 0.85 cc/g; and PA1 c) from about 0.5 to 1 weight percent, based on the catalyst of a noble metal wherein said hydrocracking catalyst have a dispersivity of the noble metal of equal or greater than about 50% by hydrogen chemisorption measurement, a surface area of greater than or equal to 700 m.sup.2 /g by BET surface area measurement, a compacted bulk density within the range of from about 0.40 to 0.58 g/cc, and a mercury pore volume within the range of from about 0.4 to about 0.7 ml/g.
