文摘
- •
USY zeolite was loaded with increasing amounts of NaCl and steamed at the typical temperature of a FCC regenerator.
- •
The samples exhibit a gradual deterioration of the texture and crystal properties with increasing load.
- •
The amorphization occurs by consuming NaCl and by evolution of HCl from the reactive media.
- •
The destruction seems to occur preferentially on six-member rings of the FAU structure.
