    Abstract

    Distributed power-supply systems have become more widespread recently. Recent distributed systems, such as fuel cells, offer high energy-use efficiency because they generate heat or hot water and electric power simultaneously. However, to avoid global warming, carbon dioxide (CO 2) from the exhaust gas has to be collected and separated, without emitting it to the atmosphere. We are investigating lithium silicate (Li 4SiO 4) (LS) because it has superior characteristics as a CO 2 absorber. Aiming at the construction of a CO 2 capture and separation system using LS, we are studying ways to process (capture and separate) the exhaust gas from distributed power-supply systems. We thought that the CO 2 capture and separate system we should design must process exhaust gases with 30% CO 2 concentration and 35 L/min flow rate and that it must capture and separate more than 50% of the CO 2 contained in the exhaust gases. However, as a result of a preliminary estimation, it became clear that the volume of the assumed CO 2 capture and separate system would be considerable. Therefore, we built a reduction model experimental setup with three reaction containers with three different aspect ratios. The results regarding container shape suggest that a long container would be advantageous..
