REY possesses such properties as high activity, excellent stability and selectivity as well as low coking orientation. By adopting NaY as the raw material, it is made through such a series of processes as rare earth treatment, ammonium salt treatment, hydrothermal ultra stabilization and chemical dealumination and silicon reinsertion. The product index is controllable by employing advanced processing techniques. The content of rare earth could also be modulated in accordance with the needs of customers.
REY Zeolite is primarily used as an active component of catalytic cracking catalysts.|
