设计了一种能测量环状、柱状或片状催化剂弯曲因子的实验装置.采用这套设备和定总压稳态技术

以及CH_4-He、N_2-He和N_2-CH_4气体体系在常温常压下

测定了Z型天然气蒸汽转化催化剂的弯曲因子.不同气体体系所得的结果彼此十分接近

该催化剂的弯曲因子大约为2.3.

An experimental equipment was designed to measure the diffusion rate of gases through the ring-shaped

cylindrical or tabletted catalyst

using this equipment and the constant total pressure

steady-state technique

the tortuosity of Z-type natural gas steam reforming calalyst has been determined

with gas systems of CH4-He

N2-He and N2-CH4 at ordinary temperature and pressure. The results obtained for different gas systems quite close each other

the tortuosity of the catalyst is about 2.3.
