Conclusions
-
1.
The influence of hydrogen on the catalytic activity of Na-mordenite, NaY, and NaA zeolites in hydrogenation reactions of acetone and benzene was studied. Hydrogen at 400–500°C practically completely deactivates the catalysts. Air or helium reduces the hydrogenating activity of the catalysts.
-
2.
Treatment of NaY with hydrogen at 190–250° C and atmospheric pressure leads to a sharp increase in the hydrogenating activity of the catalyst.
-
3.
The obtained results in conjunction with literature data permits the assumption of the existence of two forms of hydrogen, chemisorbed on zeolites in the Na form. The first of these is formed mainly at relatively low temperature and pressure and activates the catalyst, whereas the second form, which is formed at relatively high temperature and pressure, suppresses the hydrogenating activity of the zeolites.
