We have obtained zeolite Y crystals with intracrystalline trimodal porosity by base leaching of previously steamed and acid-leached material. Two distinct intracrystalline mesopore networks (~3 nm and ~30 nm, respectively) were imaged using electron tomography (3D-TEM). The crystals show high activity and close to ideal selectivity in n-hexadecane hydrocracking.
