Carbon dioxide absorbent fluid for a carbon dioxide sequestering system on a vehicle.

摘要

A carbon dioxide storage means stores the carbon dioxide released in a heat exchanger (18). The heat exchanger (18) cools the exhaust gas (16) emitted by the internal combustion engine, and includes a thermal electric generator (teg (54)) configured to couple thermally the exhaust gas chamber (50) to the absorber fluid chamber (52) in a manner effective to heat the CO2 absorbent fluid (24) by heat from the engine exhaust to release CO2 gas from the CO2 absorbent fluid (24) and generate electricity in response to a temperature difference therebetween. The CO2 absorbent fluid (24) is one of: a) an aliphatic di-functional nitrile (e.g. pimelonitrile); and b) an oligomeric poly-acrylonitrile (PAN).
