| 摘要 |
This invention relates to a composition of matter comprising an inorganic, porous crystalline phase material exhibiting, after calcination, an X-ray diffraction pattern with at least one peak at a d-spacing greater than 1.8 nm and having a benzene adsorption capacity of greater than 15 grams benzene per 100 grams of said material at 6.7 kPa (50 torr) and 25 DEG C. Preferably, the crystalline phase material has a hexagonal arrangement of uniformly-sized pores at least 1.3 nm in diameter and exhibiting, after calcination, a hexagonal electron diffraction pattern that can be indexed with a d100 value greater than 1.8 nm. |
