ジャーナル 認証ありThe development of CO2 capture technology is essential as a global warming mitigation technology that will lead to the suppression of climate change. Gas separation membranes have great potential for direct air capture (DAC), which captures CO2 directly from the atmosphere, as well as from large CO2 emission sources, due to their low energy consumption and small footprint. However, membrane–based DAC has never been considered because of its low CO2 permeance. Recently, there have been report of high CO2 permeance membranes which would be promising candidate for DAC process. In this review paper, the recent studies of membranes with high CO2 permeance are summarized and discuss with molecular design of membranes in addition to our recent efforts to improve CO2 selectivity of nanometer–thick freestanding membranes by chemical modification of the membrane surface.抄録全体を表示PDF形式でダウンロード (941K) -

ジャーナル 認証ありTo solve the global climate change, greenhouse gas mitigation technologies have been vitally important. CO2 is the primary greenhouse gas emitted by human activities, mainly combustion of fossil fuel. CO2 Capture and Storage (CCS) is one of the key technologies to reduce CO2 emission. CO2 capture by chemical absorption has been used in the Oil & Gas and chemical industries for removal of CO2 from gas streams. It is expected to be deployed to largescale carbon emission source such as thermal power plants in the near future. In this article, the issues of chemical absorption method is reviewed, and our efforts for addressing them are introduced.抄録全体を表示PDF形式でダウンロード (1010K) -

ジャーナル 認証ありKawasaki Heavy Industries, Ltd. has made R&D of a efficient CO2 capture system, Kawasaki CO2 Capture (KCC), by utilizing a solid sorbent. The greatest feature of the KCC system is the low–temperature regeneration process of CO2 with steam below 100 ℃, for example at 60 ℃, and this steam can be available from unused exhaust heat in various plants. This system allows lower energy CO2 capture comparing with the existing CO2 capture system, such as liquid amine scrubbing. In this paper, current status of KCC projects is described.抄録全体を表示PDF形式でダウンロード (926K) -

ジャーナル 認証ありPolymeric membrane gas separation technology has been successfully applied to acid gas removal for CO2 EOR natural gas applications. The field proven CO2 removal technology also attracts attention from CCUS community as a “game changer” technology or enabler. This review paper outlines the advantage of bulk CO2 removal using polymer membrane in EOR applications and industry status for challenging to CCUS applications.抄録全体を表示PDF形式でダウンロード (929K)

ジャーナル 認証ありOrganic, inorganic, and metal–based materials for membrane technologies have been studied and developed, and membranes made from some of these materials have been applied to industrial applications. In particular, polyimides have excellent fiber–forming properties with good thermal, chemical, and mechanical durability, so are used to manufacture asymmetric hollow fiber membranes for use in many membrane separation processes. This review introduces the material characteristics of polyimides, membrane properties of polyimide hollow fiber membranes, and applications as membranes for gas and vapor separation.抄録全体を表示PDF形式でダウンロード (676K)
