Fast synthesis of nanosized zeolite beta from a low-seeded, low-templated dry gel with a seeding-steam-assisted conversion method

Nanosized zeolite beta with a tuneable crystal morphology and size, rich intercrystalline mesoporosity and high catalytic activity for low-density polyethylene cracking, was fast transformed from a low-seeded, low-templated dry gel by a seeding-steam-assisted conversion method with a small quantity of water; the crystallization of zeolite beta is well induced within 28 h at a TEAOH/SiO2 of 0.1 with the aid of 1% seeds.
