"PROCESS AND APPARATUS TO PREVENT GLOBAL WARMING, AND, PROCESS TO PRODUCE ADYPIC ACID WITH REDUCED N ~ 2 RELEASE ~ WHAT CAUSES GLOBAL WARMING" A low cost and usable process in practice to prevent global warming by decomposition of N ~ 2 ~ O, where N ~ 2 ~ O, contained in a gas containing N ~ 2 ~ O to be treated, can be decomposed at a relatively low temperature; and a device for it. That is, a process to prevent global warming comprising, in a thermal or catalytic decomposition process of N ~ 2 ~ O in a gas containing N ~ 2 ~ O to be treated, dividing the gas stream containing N ~ 2 ~ O to be treated in portions, preheat a portion of it so as to exothermically decompose N ~ 2 ~ O in said gas stream to form a hot gas stream, and supply the remainder of the divided gas stream to be treated in said stream of hot gas, to continuously decompose N ~ 2 ~ O, so that global warming is prevented, and an apparatus for it.
