摘要：

The presence of hydrogenoheteropolyanions at the polyaniline surface supported H4SiW12O40 catalyst playing most probably the role of catalytically active Bronsted acid centers in cumene cracking was confirmed by the XPS measurements. These centers are partially removed by heating at 573 K in the atmosphere of dry air but easily regenerated by the water vapor introduced into the reactor in the stream of helium carrier gas.
