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 refractory inorganic oxide, into a catalyst formulation which is useful for alkylation. When utilized in a process for alkylating an aromatic with an olefin, for example in the production of cumene or ethylbenzene, the sieve catalyst shows favorable selectivity.
