Book excerpt: Energy efficient purification of hydrogen is an important technological challenge with broad applications in the chemical, petrochemical, metallurgical, pharmaceutical, textile and energy industries. Palladium-alloy membranes are particularly suited to this problem due to their high hydrogen permeability, thermal stability, and virtually infinite selectivity. In current systems hydrogen flux is observed to be inversely proportional to membrane thickness which is indicative of the interstitial diffusion mechanism of hydrogen permeation. This observation, along with the high cost of palladium, has motivated continuous efforts to decrease membrane thickness. Theoretical modeling of membrane performance predicts that as membrane thickness continues to decrease, eventually the permeation rate will no longer be limited by diffusion through the bulk Pd but will become limited by desorption from the permeate surface. If it exists, this is a vital transition to pinpoint due to the fact that below this thickness membrane operating conditions will have a drastically different effect on hydrogen permeation behavior and no additional performance enhancements will result from further decreasing thickness. A handful of experimental results in the open literature contradict these modeling predictions. A new model is developed in this work to explain these contradictions by considering the non-ideal behavior of hydrogen solution into metals which has been neglected in previous models. Additionally, it has been demonstrated that hydrogen permeation through bulk Pd depends on membrane microstructure, making deposition conditions and post-deposition thermal treatment important issues for repeatable performance.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts in this quarter were concentrated on developing vacuum processing procedures to produce thinner (4 [mu]m-thick), defect-free films over larger areas (100 cm2). We continued to test three different types of rigid supporting substrates, thermally oxidized silicon (10 cm diameter), polished borosilicate glass (10 cm diameter), and soda-lime glass (>100 cm2 areas), each representing a different cost, surface roughness, and chemistry. Mechanical integrity, defect density, and release characteristics of the films, though similar for the oxidized silicon and borosilicate glass, were distinctly different for the inexpensive soda-lime (float) glass; i.e., more sensitive to surface impurities. In general, films less than 4 [mu]m-thick were shown to be very sensitive to surface condition of the supporting substrate, particularly in the case of the soda-lime glass, to the point where surface strain overrode and dominated the intrinsic bulk stresses that are produced during the growth process. Therefore, in the near term (over the next quarter), large area films (>100 cm2) will be produced at a minimum thickness of 5 [mu]m while further development will be conducted in subsequent quarters to reduce membrane thickness in large area films. Continued hydrogen permeation experiments and characterization of 5 and 10 [mu]m-thick, Pd-Cu films, with compositions near the 60/40 (Pd/Cu phase boundary) in combination with air oxidation treatments to improve performance. Pure hydrogen permeability for an as-received, 5 [mu]m film at 400 C was determined to be 1.3 x 10−4 cm3(STP) · cm/cm2 · s · cmHg{sup 0.5} at steady state. Even a membrane ≈ 10 [mu]m-thick, exhibited a steady state hydrogen flux of 32 cm3(STP)/cm2min after air exposure, which, when normalized for DOE's Office of Fossil Energy's specified hydrogen flux with a [Delta]P of 100 psi and a permeate pressure of 50 psia, results in a flux of 155 scf/h/ft2 (exceeding the 2007 target by 55% and 77% of the 2010 target). Finally, on May 25, we presented a poster at the Hydrogen Program Review in Washington.

Book excerpt: Palladium (Pd)-based membranes have received a great deal of attention from both academia and industry thanks to their ability to selectively separate hydrogen from gas streams. The integration of such membranes with appropriate catalysts in membrane reactors allows for hydrogen production with CO2 capture that can be applied in smaller bioenergy or combined heat and power (CHP) plants, as well as in large-scale power plants. Pd-based membranes are therefore regarded as a Key Enabling Technology (KET) to facilitate the transition towards a knowledge-based, low-carbon, and resource-efficient economy. This Special Issue of the journal Membranes on “Pd-based Membranes: Overview and Perspectives” contains nine peer-reviewed articles. Topics include manufacturing techniques, understanding of material phenomena, module and reactor design, novel applications, and demonstration efforts and industrial exploitation.

Available in PDF, EPUB and Kindle. Book excerpt: Carbon capture and storage (CCS) has been considered as a practical way in sequestering the huge anthropogenic CO2 amount with a reasonable cost until a more pragmatic solution appears. The CCS can work as a bridge before fulfilling the no-CO2 era of the future by applying to large-scale CO2 emitting facilities. But CCS appears to lose some passion by the lack of progress in technical developments and in commercial success stories other than EOR. This is the time to go back to basics, starting from finding a solution in small steps. The CCS technology desperately needs far newer ideas and breakthroughs that can overcome earlier attempts through improving, modifying, and switching the known principles. This book tries to give some insight into developing an urgently needed technical breakthrough through the recent advances in CCS research, in addition to the available small steps like soil carbon sequestration. This book provides the fundamental and practical information for researchers and graduate students who want to review the current technical status and to bring in new ideas to the conventional CCS technologies.
