This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymeric facilitated transport membranes (FTMs) driven by reversible amine-CO2 reactions were developed in this study for selective CO2 separation from flue gas (CO2/N2) and syngas (CO2/H2). For post-combustion carbon capture, a FTM was synthesized in a composite membrane configuration with a 170 nm selective layer coated on a nanoporous substrate. In the selective layer, polyvinylamine with amine-sites covalently bonded to the polymer backbone was used as fixed-site carrier and an amino acid salt, synthesized by deprotonating sarcosine with 2-(1-piperazinyl)ethylamine, was blended as mobile carrier. Multi-walled carbon nanotubes wrapped by a copolymer poly(vinylpyrrolidone-co-vinyl acetate) were dispersed in the selective layer as reinforcement fillers to refrain the selective layer penetration upon vacuum suction. The membrane demonstrated a CO2 permeance of 1451 GPU (1 GPU = 10-6 cm3(STP)·cm-2·s-1·cmHg-1) and a CO2/N2 selectivity >140 at testing conditions relevant to this separation modality. A field trial with 1.4 m2 spiral-wound membrane modules fabricated from this FTM was conducted with actual flue gas at National Carbon Capture Center in Wilsonville, AL. The separation performances of the modules agreed well with those of the lab-scale flat-sheet membranes. A 500-h stability was demonstrated in spite of the interference of system upset and flue gas outage.

Download or read book Carbon Dioxide selective Membranes and Their Applications in Hydrogen Processing written by Jian Zou and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: In this work, new CO2-selective membranes were synthesized and their applications for fuel cell fuel processing and synthesis gas purification were investigated. In order to enhance CO2 transport across membranes, the synthesized membranes contained both mobile and fixed site carriers in crosslinked poly(vinyl alcohol). The effects of crosslinking, membrane composition, feed pressure, water content, and temperature on transport properties were investigated. The membranes have shown a high permeability and a good CO2/H2 selectivity and maintained their separation performance up to 170°C. One type of these membranes showed a permeability of 8000 Barrers and a CO2/H2 selectivity of 290 at 110°C. The applications of the synthesized membranes were demonstrated in a CO2-removal experiment, in which the CO2 concentration in retentate was decreased from 17% to 10 ppm. With such membranes, there are several options to reduce the CO concentration of synthesis gas. One option is to develop a water gas shift (WGS) membrane reactor, in which both WGS reaction and CO2-removal take place. Another option is to use a proposed process consisting of a CO2-removal membrane followed by a conventional WGS reactor. In the membrane reactor, a CO concentration of less than 10 ppm and a H2 concentration of greater than 50% (on dry basis) were achieved at various flow rates of a simulated autothermal reformate. In the proposed CO2-removal/WGS process, with more than 99.5% CO2 removed from the synthesis gas, the CO concentration was decreased from 1.2% to less than 10 ppm (dry), which is the requirement for fuel cells. The WGS reactor had a gas hourly space velocity of 7650 h−1 at 150°C and the H2 concentration in the outlet was more than 54.7% (dry). The applications of the synthesized CO2-selective membranes for high-pressure synthesis gas purification were also studied. We studied the synthesized membranes at feed pressures 200 psia and temperatures ranging from 100-150°C. The effects of feed pressure, microporous support, temperature, and permeate pressure were investigated using a simulated synthesis gas containing 20% carbon dioxide and 80% hydrogen.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Hydrogen is produced in large scale by steam reforming followed by water-gas-shift reaction, which yields a product stream consisting mainly of H2 and CO2. Purification of H2 from other gaseous compounds, mainly CO2, with significantly improved energy and cost efficiencies therefore becomes a crucial step for hydrogen economy that could ultimately provide hydrogen as a clean, renewable fuel as well as versatile chemical with wide commercial uses, reduce the reliance of modern industries on petroleum, and restrain global greenhouse gas emissions. Facilitated transport membranes are well suited for CO2/H2 separation due to high selectivity accompanied with high CO2 permeability, H2 product recovery at high pressure, and low energy and cost consumptions. The objective of this research is to develop advanced CO2-selective facilitated transport membranes with desired properties for practical gas separation applications.
