摘要
催化裂化(FCC)过程中会产生大量失活的废催化剂。为了循环利用此种废弃物,本文将高温活化过的废FCC催化剂作为载体,制备负载型非贵金属铁基催化剂,并进行CO催化氧化性能的考察。结果表明,当催化剂用量为3g,反应空速为2000mL·h^(-1)·g^(-1),负载量为50%时,经O_(2)预处理后的铁基催化剂,在350℃下,CO能够完全转化。
During catalytic cracking(FCC)process,a large amount of deactivated waste catalyst is produced.In order to recycle this waste,the waste FCC catalyst was activated at high temperature as a carrier to prepare a supported non-noble metal Fe-based catalyst for CO catalytic oxidation.The results show that when the amount of catalyst is 3g。the reaction space velocity,2000mL·h^(-l)·g^(-1),and the loading amount,50%,the CO conversion can reach 100%at 350℃ on the catalyst after O2 pretreatment.
