Transformation of n-hexane over microporous molecular sieves: Studies overMeAPO-11 and MeAPSO-11

CoAPO-11, MKAPO-11, ZnAPO-11, COAPSO-11, ZnAPSO-11 and MgAPSO-11 samples we re synthesized by hydrothermal methods and characterized. The samples were loaded with 0.5 wt.% Pt and tested for their catalytic activities in the is omerization of n-hexane. All the samples exhibited catalytic activities and selectivities for isomerization comparable to that of SAPO-11. The selecti vities for the different monomethyl and dimethyl isomers are rationalized o n the basis of shape selectivity and acidities of different samples.
