Group C⁺ particles, Group C particles after nano‐modulation, with extremely large specific surface area, have been shown to exhibit extraordinarily good fluidization quality with superiorly high bed expansion, significantly increasing gas holdup in the bed. As a first attempt, Group C⁺ particles were used as catalysts in a fluidized bed reactor (C‐plus FBR) to evaluate the reaction performance and were compared to that using Group A particles. C‐plus FBR could achieve a much higher reaction conversion, up to 235% of that using Group A particles. The contact efficiency for Group C⁺ particles is much higher, being 330% more than that for Group A particles. The greater contact efficiency is due to both larger specific surface area and higher bed expansion, providing larger gas–solid interfacial area and longer gas residence time. Conclusively, Group C⁺ particles with superior fluidization quality and reaction performance do have huge potential in gas‐phase catalytic reactions.

C +组颗粒：通过纳米调制提高流化床反应器的效率

C ⁺粒子（纳米调节后的C粒子）具有非常大的比表面积，已显示出极高的流化质量，并具有极高的床膨胀率，显着增加了床中的气体滞留率。首次尝试将C ⁺组颗粒用作流化床反应器（C + FBR）的催化剂，以评估反应性能，并与使用A组颗粒进行比较。C + FBR可以实现更高的反应转化率，最高可达使用A组颗粒的转化率的235％。C ⁺组的接触效率颗粒要高得多，比A组颗粒高330％。更高的接触效率归因于更大的比表面积和更高的床膨胀率，从而提供了更大的气固界面面积和更长的气体停留时间。结论是，具有优异流化质量和反应性能的C ⁺组颗粒在气相催化反应中确实具有巨大的潜力。
