Abstract
This invention presents a novel MgAPSO molecular sieve, containing a critical range of magnesium: in the sieve framework and having a small crystallite size, which is particularly active for hydrocarbon conversion. The sieve advantageously is incorporated, along with a platinum-group metal, into a catalyst formulation which is useful 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.
