| Abstract: | Two SAPO-34 samples were hydrothermally synthesized at 473 and 573 K respectively with diethylamine as the structure-director. SEM and XRD results showed that the SAPO-34 crystal size, crystallinity, BET surface area and pore diameter increased with increasing the crystallization temperature. The highest permissible calcination temperature and the highest permissible steam treatment temperature increased with increasing the crystallization temperature. |

| Keywords: | diethylamine hydrothermal method SAPO-34 calcination steam treatment |
