摘要：

The optimized regeneration of coked H-Y zeolite was studied by thermogravimetry using a multiple heating rate integral kinetic method. It was shown that, in order to remove half the coke deposited on zeolite in a period of 1 h, it would be necessary to carry out thermo-oxidation at 742 K. In the same space of time, practically complete regeneration took place at 792 K.
