The results show that the regenerated catalysts have a little increase in the pore volume and average pore size and a slight decrease in the surface area and acidity compared with the fresh FC-18 catalysts.

采用物理吸附仪、X光衍射仪(XRD)、红外光谱(IR)、等离子发射光谱(ICP)、无机分析、元素分析仪对再生前后FC-18催化剂的物化性质和性能变化进行了测试和表征,探讨了催化剂失活的原因。
