制备了不同孔结构的Ni-CaO-ZrO 2催化剂，并对甲烷CO2重整反应进行了考察。结果表明，具有介孔骨架的催化剂具有较高的活性和稳定性。特别地，在连续运转的一段时间内没有观察到失活。表征结果表明，介孔结构的“限制效应”阻止了Ni颗粒在反应过程中的烧结，具有介孔骨架的催化剂表现出更好的催化性能和抗结焦性能。
Ni–CaO–ZrO2 catalysts with different pore structures were prepared and tested for CO2 reforming of methane. It was found that the catalyst with a mesoporous framework showed both high activity and stability. In particular, no deactivation was observed at a period of run on stream. The characterization confirmed that the “confine effect” of the mesoporous structure prevented Ni particles from sintering during reaction, and as a result, the catalyst with such a mesoporous framework showed a better catalytic performance and resistance to coking.
