- Catalytic cracking is an important secondary processing of crude oil and plays a pivotal role in the refining industry.
- a heavy fraction such as a vacuum distillate or a heavy component residue is reacted in the presence of a catalyst to be converted into a high value-added product such as liquefied gas, gasoline, diesel, etc., which is usually required to be used in this process.
- High cracking activity catalytic material Microporous zeolite catalyzed materials are widely used in the petroleum refining and processing industry due to their excellent shape-selective catalytic properties and high cracking reactivity.
- ⁇ -type molecular sieves have been the main active component of catalytic cracking catalysts since they were first used in the 1960s.

- the rare earth content in the product is usually lower than the total rare earth input. Even if more rare earth ions are located in the small cage, it is inevitable that some rare earth ions will still be present in the super cage.
