Magnesium containing non zeolitic molecular sieve and use as isomerization catalyst.

摘要

A novel MgAPSO molecular sieve, containing a critical range of magnesium in the sieve framework, which is particularly active for hydrocarbon conversion is disclosed. The sieve advantageously is incorporated, along with a platinum-group metal, into a catalyst formulation which is useful in conversion of hydrocarbons and particularly for isomerization. When utilized in a process for isomerizing a non-equilibrium mixture of xylenes containing ethylbenzene, a greater yield of para-xylene is obtained compared to prior-art processes.
