MTW-zeolite as support for second stage hydrocracking catalysts with improved selectivity and cold flow property of distillate products

A hydrocracking catalyst comprising a catalyst support base of alumina, an amorphous silicia-alumina, a USY zeolite and ZSM-12, wherein the hydrocracking catalyst comprises a modifying agent, and wherein the modifying agent is selected from the group consisting of compounds represented by structures (1) through (4), and condensated forms thereof:

• wherein:
• (1) R1, R2 and R3 are independently selected from the group consisting of hydrogen;
• hydroxyl;
• methyl;
• amine;
• and linear or branched, substituted or unsubstituted C1-C3 alkyl groups, C1-C3 alkenyl groups, C1-C3 hydroxyalkyl groups, C1-C3 alkoxyalkyl groups, C1-C3 aminoalkyl groups, C1-C3 oxoalkyl groups, C1-C3 carboxyalkyl groups, C1-C3 aminocarboxyalkyl groups and C1-C3 hydroxycarboxyalkyl groups;
• (2) R4 through R10 are independently selected from the group consisting of hydrogen;
• hydroxyl;
• and linear or branched, substituted or unsubstituted C2-C3 carboxyalkyl groups;
• and
• (3) R11 is selected from the group consisting of linear or branched, saturated and unsaturated, substituted or unsubstituted C1-C3 alkyl groups, C1-C3 hydroxyalkyl groups, and C1-C3 oxoalkyl groups.
