Using the method of thermal desorption of ammonia, we have studied the acidity of hydrogen forms of a number of zeolites: type Y, ultrahigh silica TsVK, synthetic and natural mordenite (M). The hydrogen forms of the TsVK and M zeolites have similar acidity spectra. But for HTsVK, the overall concentration of acidic centers is sufficiently lower than for HM, including weak centers (2.5–3 times) and strong centers (1.5 times). The concentration and strength distribution of acidic centers are very close in samples of synthetic and natural mordenite. |
