通过考察金属氧化物 ( Mg O、Fe2 O3等 )对 FCC工艺中非贵金属助燃剂 Cu O- Ce O2 /Al2 O3的 Al2 O3载体改性所引起载体结构的变化 ,研究对助燃剂抗硫、硫转移性能的影响。结果表明 ,由于改性载体中所形成的类尖晶石结构使得催化剂具有较好的抗硫性能和一定的硫转移能力。
By investigating the change of the structure of the support caused by the modification of the Al 2 O 3 carrier of non-noble metal combustion improver Cu O-Ce O 2 / Al 2 O 3 in the FCC process, the effect of the oxidizer on the anti-sulfur and sulfur Effect of transfer performance. The results show that due to the spinel-like structure formed in the modified support, the catalyst has better sulfur resistance and sulfur transfer ability.
