HEAT TREATING A MOLECULAR SIEVE AND CATALYST

摘要

Disclosed is a method of heat treating a molecular sieve. The method compris es 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 o f template effective to cover catalytic sites within the molecular sieve. A catalyst composition is also provided which comprises a molecular sieve havi ng 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 compositi on exhibits a Davison Index of not greater than 30.
