Abstract

This study investigates a compact palladium membrane module (CPMM) for hydrogen purification, assembled by diffusion bonding at a low-temperature (450 °C). This CPMM resulted in hydrogen (H) flux of 18.3 mL cm min with H/N selectivity of over 1100. The H purification test using a 60% H/40% CO mixed gas confirmed that the CPMM can separate H with a concentration of more than 99%, with a pressure difference of 5 bar. Moreover, the volume of the diffusion bonded membrane module is decreased by 81.4% than the flame-type membrane module pre-studied in our laboratory.

摘要

本研究对一种用于氢气提纯的紧凑型钯膜组件（CPMM）进行了研究，该组件通过低温（450°C）扩散连接组装而成。这种CPMM的氢气（H）通量为18.3 mL cm min，H/N选择性超过1100。使用60% H/40% CO混合气体进行的氢气提纯测试证实，CPMM在5巴的压差下能够分离出浓度超过99%的氢气。此外，与我们实验室之前研究的火焰型膜组件相比，扩散连接膜组件的体积减少了81.4%。
