ジャーナル オープンアクセスThe membrane reformer is a next generation reformer mainly for on-site hydrogen stations for fuel cell vehicles. In the membrane reformer, hydrogen generated by steam methane reforming of natural gas permeates through a palladium hydrogen separation membrane. Since hydrogen generation and separation proceed simultaneously in a single reactor without limitation of equilibrium, the membrane reformer is simpler, more compact and more energy efficient than a conventional reformer. Tokyo Gas Co., Ltd. and Mitsubishi Heavy Industries Ltd. have developed a 40 Nm3/h-H2 -class membrane reformer system with 81.4% HHV efficiency. In addition, Tokyo Gas Co., Ltd. and NGK Spark Plug Co., Ltd. have developed a compact and low cost module with membrane on catalyst for the membrane reformer.抄録全体を表示PDF形式でダウンロード (899K) -

ジャーナル オープンアクセスOxygen permeable membranes have been attracting much attention for a variety of applications such as hydrocarbon reforming. This article describes the concept of oxygen permeable membranes based on mixed oxide-ion and electronic conductors and trend in material development. To date, perovskite-type oxides such as Ba0.5Sr0.5Co0.8 Fe0.2O3 -δ and dual-phase-type membranes such as (Ce0.85Sm0.15) O2-15vol% MnFe2O4 showing an oxygen permeation rate of 8 ∼ 10 μmol·cm-2·s-1 (≈10 ∼ 13 sccm·cm-2) under CH4 reforming has been developed. Hydrocarbons such as methane and dodecane can be reformed by using these oxygen permeable membranes under dry and low S/C conditions.抄録全体を表示PDF形式でダウンロード (949K) -

ジャーナル オープンアクセスHydrogen is attracting attention as a clean fuel that produces no carbon dioxide emissions at the stage of use. Hydrogen could be produced from fossil fuels using existing equipment in refineries, but in such production schemes, the hydrogen recovery rate decreases when purity is increased to 99.99% or higher as is required for fuel cells. To solve this problem, we developed a new hydrogen purification system with a hybrid-type membrane that features CO2 membranes and H2 membranes arranged alternately, and which utilizes the high temperature and high pressure in the hydrogen production unit. This system achieves increased recovery of high-purity hydrogen compared to existing technologies. Such a system requires a highly stable and CO2-selective membrane. As ionic liquids (ILs) are known for their negligible volatility, we modified the chemical structure of some ILs to increase their CO2 selectivity. We thus set out to develop a CO2 separation membrane incorporating our novel ILs. The membranes we developed show remarkably high CO2/H2 selectivity from mixed gases of CO2 and hydrogen.抄録全体を表示PDF形式でダウンロード (1119K) -

ジャーナル オープンアクセスIn this study, we developed a novel membrane reactor consisted of CO shift catalysts and a membrane for CO2 separation. First, we developed facilitated transport membranes for CO2 separation. We tested several carriers to achieve high CO2 permeance (1 × 10-4 mol /m2 s kPa) and high CO2/H2 selectivity (100). We successfully achieved the target values even at the elevated temperature (160 °C). In addition, the developed membrane had good stability. It was confirmed that high performance was maintained stably for 400 hours at 160 °C. Secondly, we developed CO shift catalysts, which have high activity for the CO shift reaction at low temperature region. As a result, we succeeded in the development of both precious metal-based catalysts, and Cu-based catalysts. Thirdly, a membrane reactor could be fabricated by combining the developed CO2 selective membranes and CO shift catalysts. Observed CO and CO2 concentrations at the feed-side exit of the membrane reactor were lower than 10 ppm and 1%, respectively. Using membrane reactor it is possible to reduce both CO and CO2 to lower than equilibrium level. Finally, we performed trial design of the total system of a hydrogen station equipped with the developed membrane reactor and evaluated the effect of the membrane reactor on downsizing of the total system and improvement of efficiency. kn-abstract=抄録全体を表示PDF形式でダウンロード (1379K) -

ジャーナル オープンアクセスTechnology Roadmap compiled by JPEC focuses on membrane technology as one of advanced energy-saving processes. Organic membranes have already been put into practical use in the petroleum refining industry for gasses, such as for the separation of hydrogen or carbon dioxide. Inorganic membranes, however, which are expected to be more advantageous to separate specific hydrocarbons than organic membranes in terms of high temperature tolerance. Information here provided from overseas organizations will be utilized for discussion on JPEC future project.抄録全体を表示PDF形式でダウンロード (1365K)

ジャーナル 認証ありWe proposed a method for purifying proteins based on an interaction between dually-immobilized affinity ligands and dually-tagged proteins. Streptavidin (SA) and nickel (Ni) ions as two kinds of ligands were immobilized to the polymer brush grafted onto a porous hollow-fiber membrane. Whereas, green fluorescent protein (GFP) containing both streptavidin binding peptide (SBP) and poly histidine tag (His-tag) as two kinds of tags was genetically produced. The resultant dually-tagged protein solution was permeated through the pores of the dual-affinity-ligands- immobilized porous hollow-fiber membrane. The dual-affinity ligands and dually-tagged proteins were found to fit on the polymer chain grafted onto the pore surface at a binding efficiency 2%.抄録全体を表示PDF形式でダウンロード (861K)
