Nanoseed-assisted synthesis of nano-sized SAPO-34 zeolites using morpholine as the sole template with superior MTO performance.

Nano-sized SAPO-34 catalysts have been for the first time prepared using morpholine as the sole template by using a one-pot nanoseed-assisted method. The obtained nano-sized SAPO-34 catalysts exhibit about 4-fold prolonged lifetime and nearly 5% increased selectivity for ethylene and propylene compared to conventional micron-sized counterparts in methanol-to-olefin reactions.
