摘要
该方法利用缺O^(2-)离子磁铁矿在290～350℃经H_2活化使CO_2分解。分解产生的碳沉积在磁铁矿上并可以在400℃下与水蒸气反应生成H_2,在400～600℃下与H_2反应生成CH_4。这种方法可以使工业废气、汽车尾气等排放的CO_2几乎100％分解,是一种有前景的可以控制CO_2排放并使其再资源化的技术。
A good deal of the concern over pollution from coal-fired plants,transportation, industry and other sources(residential and commercial) is directed at production of carbon dioxide,which is linked to future global warming. It may well be necessary to have suitable technology available to further mitigate the effects.The paper introduces a new pathway for reducing CO_2 emiss ion by decomposing CO_2 completely at 290—350℃ with the oxygen dificient magnetite which had been prepared by passing the H_2 gas through the magnetite powder at the same temperature.The CO_2 in the exhaust gas from the industry,gasoline engine,and so on could been decomposed completely(～100％) in the reaction,while the carbon deposited on the magnetite.Then the carbon was reacted with H_2O(400℃) and H_2(400～600℃), H_2 and CH_4 were generated, respectively.
