摘要：
The effects of the pretreatment methods of cyclic contamination-oxidation-reduction cycle and traditional impregnation contamination-100% water vapor aging on the performance of FCC cata-lysts were compared. The characteristics of metal distribution on the catalysts prepared by the two pre-treatment methods as well as FCC ECat were investigated by means of optical microscopy and electron probe microscope analysis. The experimental results showed that the product distribution of the two types of aged catalysts is different when the microactivity is comparative. The product distribution of catalyst prepared by the cyclic contamination aging method is good,close to the level of ECat. The aged catalyst prepared by traditional method have no metal age distribution,while metals on circulating pollu-tion aging catalyst have age distribution and is close to ECat.%對比了循環(huán)污染-氧化還原循環(huán)的預(yù)處理方法與傳統(tǒng)的浸漬污染-100%水蒸氣老化的預(yù)處理方法對催化劑性能的影響,利用光學(xué)顯微鏡和電子探針等方法,考察了循環(huán)污染老化制備的老化劑、傳統(tǒng)方法制備的老化劑以及工業(yè)平衡劑上的金屬分布特點(diǎn).結(jié)果表明:當(dāng)微反活性相當(dāng)時,兩種方法制備的老化劑上產(chǎn)品分布差別較大,循環(huán)污染老化法制備的老化劑上產(chǎn)品分布較好,更能接近工業(yè)平衡劑水平;傳統(tǒng)方法制備的老化劑上金屬無年齡分布,循環(huán)污染老化法制備的老化劑上含屬有年齡分布,與工業(yè)平衡劑更接近.
