2019, Master of Science, Ohio State University, Chemical Engineering.
Most of the hydrogen is produced from natural gas steam reforming process followed by water-gas-shift (WGS) reaction for syngas purification. The produced mixed syngas, consisting of mainly H2 and CO2, needs to be separated to complete the conversion of CO and obtain high purity H2, which can act as a clean, renewable fuel gas for widely commercial uses. Mixed-matrix membrane incorporated nanofillers containing CO2 carriers is one kind of facilitated transport membrane, which shows remarkable transport performance and excellent stability operated under high pressures and high temperature. In the present work, amino-functionalized multi-walled carbon nanotubes (AF-MWNTs) were chosen as the mechanical reinforcing filler to enhance the membrane stability and as the CO2 carrier to facilitate CO2 transport. Variable amounts of AF-MWNTs were incorporated to crosslinked PVA-poly(siloxane)/amine membranes to synthesize the CO2-selective mixed-matrix membranes. The membrane containing 10 wt.% MWNTs demonstrated optimal stable CO2 permeability of 1090 Barrer and CO2/H2 selectivity of 48 for the 100-h test at 1.5 MPa and 107 °C. The primary purpose of this work was to investigate out the effect of AF-MWNTs loading in the mixed-matrix membrane under high pressure in order to obtain the optimal transport performance. Thus, this research was considered to contribute to the syngas purification of industrial interest.
