dc.description.abstract | Hydrogen separation from biomass-derived syngas is a critical step in the utilization of gasification technology. Compared with the traditional methods, membrane technology provides an effective and low-cost solution for adjusting the gas composition and collecting H-2 in syngas environments. In this study, a zeolitic imidazolate framework-8 (ZIF-8)-based membrane, which is a potential candidate for H-2 separation from biomass-derived syngas, was successfully fabricated through the seeded (secondary) growth method and the subsequent post-treatments. The prepared ZIF-8 membrane exhibited a modest H-2 separation performance for H-2/CO2 and H-2/CO, with separation factors of 4.95 and 6.08, respectively, and a H-2 permeance of 7.81 x 10(-8) mol m(-2) s(-1) Pa-1 at 200 degrees C in the simulated biomass-derived syngas environments (H-2/CO2/CO) with the presence of steam. In particular, the H-2/CO2 and H-2/CO separation factors were increased by 36% and 97%, respectively, with respect to those obtained through bare supports. Despite the promising H2 perm-selectivity, the H-2/CO2 and H-2/CO separation factors of ZIF-8 membranes at 200 degrees C under water-containing syngas environments were maintained up to 10 h but the longer exposure led to the gradual degradation and eventual reduction toward those of bare supports after 15 h seemingly due to the water-involved membrane degradation. This study provides the availability and limitation of ZIF-8 membranes for H-2 separations in stimulated biomass-derived syngas environments. (C) 2015 Elsevier Inc. All rights reserved. | - |
