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...http://www.google.co.uk/patents/US5478787?utm_source=gb-gplus-sharePatent US5478787 - Discrete molecular sieve and use
