英文摘要hydrated-based separation process has recently raised as a novel technology for hydrogen (h-2) purification from mixture gases containing carbon dioxide (co2). however, the practical application requires suitable hydrate formation condition, hydrate formation rate, gas selectivity, gas storage capacity and so on. this work presents the effect of synergic additives on the hydrate-based syngas purification process based on the thermodynamic, kinetic, purification characteristic studies as well as microcosmic structure analysis. the synergic additives comprise traditional hydrate promoter (tetra-n-butyl ammonium bromide, tbab) and gas solvent (dimethyl sulfoxide, dmso). 40.2 mol% co2/h-2 binary mixtures were selected as the simulated syngas. the results show that the synergic additives (tbab-dmso) can reduce the equilibrium hydrate formation pressure of the simulated syngas by 80%. compared to single tbab for the hydrate-based purification process, the synergic additives could improve the gas consumption rate of the unit system, gas storage capability and gas selectivity by about 32%, 105% and 51% respectively, and decrease the loss ratio of h-2 by 1.45%. the raman analysis reveals that the simulated syngas forms semiclathrate framework with tbab-dmso. dmso only performs as a gas solvent during the gas dissolution and diffusion process, and not participates in the hydrate framework formation. copyright (c) 2015, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
