BETA ZEOLITE AND METHOD FOR PRODUCING THE SAME |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide beta zeolite and a method for producing the zeolite with which an environmental load can be reduced to the minimum without using a structure regulating agent as far as possible. <P>SOLUTION: The beta zeolite is an aluminum-rich zeolite having an SiO<SB>2</SB>/Al<SB>2</SB>O<SB>3</SB>ratio of 10 to 16. The zeta zeolite is characterized by having a BET specific surface area of 500 to 700 m<SP>2</SP>/g, a micropore specific surface area of 350 to 500 m<SP>2</SP>/g and a micropore volume of 0.15 to 0.25 cm<SP>3</SP>/g as measured in a state of a sodium type zeolite. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
