초록

Due to the increasing demand for propylene, highly selective propylene production from ethylene using small pore zeolite has received significant attention. However, rapid catalyst deactivation due to coke deposition on the catalyst impedes effective propylene production in industry. Therefore, it is essential to develop a low-temperature regeneration ethylene-to-propylene (ETP) catalyst with stable catalytic activity. To achieve such a catalyst, various hydrocracking metal species and phosphorus-supported SSZ-13 were prepared and evaluated using a one-pass ETP and ETP-Regen test. The optimized catalyst NiO(1.0)-P(0.6)-SSZ-13 exhibited a constant, excellent propylene yield of over 70 wt% with 90 wt% of propylene selectivity over ETP reaction and consecutive ETP-Regen cycles. The unprecedented catalytic performance of NiO(1.0)-P(0.6)-SSZ-13 was ascribed to the synergistic effect of NiO and P components, where nickel is responsible for catalyst recovery through effective coke removal, while phosphorus plays an essential role in size-selective diffusion.
