| 摘要 |
Molecular sieves comprising (1) phosphorus oxide; (2) a first oxide comprising an oxide of silicon, germanium or mixtures thereof; and (3) a second oxide comprising an oxide of aluminum, boron or mixtures thereof, said molecular sieve having a mole ratio of the first oxide to the second oxide of greater than 1, containing at least about 10 weight percent phosphorus oxide in the crystal framework, and having pores greater than 5 Å in diameter are useful as catalysts in hydrocarbon conversion reactions.
