摘要: 研究了载体的条径、条长分布和载体形态对空隙率的影响。结果表明:在实验室测定条件下,条径越大、平均条长越长,载体空隙率越高;不同形态载体的实部占比不同,实部占比与空隙率呈反比关系;载体堆密度与实部占比有关,也与空隙率有关。通过对形态与效率因子、强度和空隙率的关系进行研究,提出了对载体形态进行模拟和优化的思路,可得到给定条件下最优的催化剂形态。

Abstract: This study investigates the effects of the strip diameter, strip length distribution, and morphology of carriers on the void fraction. The results demonstrate that under laboratory measurement conditions, the larger the strip diameter and the longer the average strip length, the higher the void fraction of the carrier. Carriers with different morphologies exhibit varying proportions of the real part, and there is an inverse relationship between the proportion of the real part and the void fraction. The carrier pile ratio is related to both the proportion of the real part and the void fraction. By examining the relationships between morphology and efficiency factors, strength, and void fraction, a conceptual approach for simulating and optimizing carrier morphology has been proposed to achieve the optimal catalyst morphology under specified conditions.
