Disclosed is a method of heat treating a molecular sieve. The method comprises providing a template-containing molecular sieve, heating the molecular sieve under conditions effective to remove a portion of the template from the molecular sieve, and cooling the heated molecular sieve to leave an amount of template effective to cover catalytic sites within the molecular sieve. A catalyst composition is also provided which comprises a molecular sieve having a microporous structure and a binder, wherein between 10 and 90 vol % of the microporous structure is occupied by a material, the material comprising a template or a carbonaceous residue of a template, and the catalyst composition exhibits a Davison Index of not greater than 30.
A method of heat treating a molecular sieve comprising providing a molecular sieve containing a template within a microporous structure, heating the molecular sieve under conditions effective to remove a portion of the template from the microporous structure, and leave an amount of template or a degradation product thereof effective to cover catalytic sites within the microporous structure, wherein the molecular sieve is comprised within a catalyst composition which further comprises a binder, and the heating is effective to provide a catalyst composition having a Davison Index of not greater than 30.
