A study has been made of the relationships governing the conversion of
n-hexane on zeolite TsVN and its specimens steam-treated at 600 degre
es C. It is shown that the differences in the cracking rates with diff
erent conversions in the range X = 10-20% on zeolites may be very pron
ounced. Quantitative estimates have been obtained for the activity of
the specimens studied, and the influence of the heat and steam treatme
nt time on the catalytic properties of TsVN has been established. (C)
