Key Points

To introduce and verify interconnected intracrystalline mesoporosity in commercial zeolite Y crystals to relieve diffusion barriers in catalytic cracking.
Engineered size-tailored mesopores into commercial zeolite Y crystals using a surfactant-templated post-synthetic mesostructuring treatment.
Characterized pore connectivity and intracrystalline structure using electron tomography, 3D rotation electron diffraction, and high-resolution gas adsorption with hysteresis scanning and density functional theory.
Evaluated catalytic cracking performance and product distribution in both laboratory tests and commercial refinery trials.
Advanced structural imaging and diffraction confirmed the intracrystalline presence and high connectivity of the newly introduced mesoporous channels.
Performance testing demonstrated significantly improved catalytic selectivity, increasing the yield of valuable liquid fuels while decreasing coke and unconverted feed.
