摘要：
The reaction of n-butane with ''reactor-equilibrated'' (VO)(2)P2O7 based catalysts activated with different oxygen treatments has been investigated using a combination of high speed transient response and temperature programmed techniques. Results indicate that (VO)(2)P2O7 has a unique ''storage/supply'' system capable of adsorbing oxygen and efficiently channeling it to the active catalytic site. It is proposed that storage occurs via the transformation of (VO)(2)P2O7 into V+5 compounds and the supply mechanism involves the reverse reaction.
