Abstract
Disclosed herein is a method of making activated EU-2 zeolite, including: pores having a diameter of 30 to 40 Å while maintaining the crystal structure of the EU-2 zeolite; and pores having a diameter of 40 to 200 Å, wherein the volume of the pores having a diameter of 30 to 40 Å is 0.01 to 0.06 cc/g, and the volume of the pores having a diameter of 40 to 200 Å is 0.07 to 0.4 cc/g.
Claims9
A method of preparing an activated EU-2 zeolite, comprising the steps of:
- a) hydrothermally synthesizing an EU-2 zeolite;
- and
- b) activating the EU-2 zeolite by bringing the EU-2 zeolite into contact with an aqueous alkali solution before or after calcining the EU-2 zeolite,
- wherein the activated EU-2 zeolite comprises:
- pores having a diameter of 30 to 40 Å while maintaining a crystal structure of the EU-2 zeolite;
- and
- pores having a diameter of 40 to 200 Å,
- wherein a volume of the pores having a diameter of 30 to 40 Å is 0.01 to 0.06 cc/g, and a volume of the pores having a diameter of 40 to 200 Å is 0.07 to 0.4 cc/g.
