ABSTRACT:
A hydrocracking catalyst and a process using it are described. The catalyst comprises a dealuminated zeolite bound into a highly porous amorphous support matrix. The catalyst is characterized by its low piece density and a bimodal pore distribution, with the unfinished catalyst having a sizeable amount of macropores having diameters between 5,000 and 9,000 Angstroms. A high amount of mesopores between about 56 and about 297 Angstroms is also desired. The presence of pores between 300 to 500 Angstroms and greater than 10,000 Angstroms in diameter is minimized.
