Method and device for decomposing N2O |
摘要 |
<p>A low-cost and practically useful method for preventing global warming by decomposing N2O wherein N2O contained in an N2O-containing gas to be treated can be decomposed at a relatively low temperature; and an apparatus therefor. That is, a method for preventing global warming comprising, in a process of thermally or catalytically decomposing N2O in an N2O-containing gas to be treated, dividing the N2O-containing gas stream to be treated in portions, preheating a portion thereof so as to exothermally decompose N2O in said gas stream to form a hot gas stream, and supplying the remainder of the divided gas stream to be treated into said hot gas stream to thereby continuously decompose N2O, so that global warming is prevented; and an apparatus therefor. <IMAGE></p> |
