Preparation of a compact microchannel membrane module for hydrogen purification |
| 초록 |
This study investigates a compact Micro-channel-reactor (MCR) type membrane module assembled by the diffusion bonding method at the low-temperature (450 °C) for hydrogen purification. In order to perform the low-temperature diffusion bonding of the membrane module, the surfaces of SUS plates were modified with blasting, Ni-Cu deposition and thermal treatment in sequence, resulting in commissure dramatically increased the average-surface roughness (Ra) and surface-area. The surface modified plates made them well bonded at low-temperature. The prepared compact MCR type membrane module showed that the hydrogen flux was 18.3 ml cm-2 min-1 at the pressure difference of 0.1 MPa with a H2/N2 selectivity was over 1100. The hydrogen purification test using a 40% CO2/ 60% H2 mixture gas confirmed that the MCR type membrane module is capable of separating hydrogen with concentration of more than 99% at 400 °C, pressure difference 0.5 MPa and the feed gas rate of 1.5 L min-1. |
