A SAPO-11 silicoaluminophosphate molecular sieve with stable crystal structure was synthesized for the first time. After removing template by calcination, its crystal space group still retains Icm2 which the as-synthesized has. The catalyst deriving from the present SAPO-11materials shows higher isomerization selectivity and higher paraffin hydroisomerization yield than those reported elsewhere.
