摘要: SAPO-31 molecular sieve was synthesized using dibutylamine as the organic template and characterized by XRD, SEM, TPD of NH 3 , DTA-TGA, sorption measurements IR spectroscopy. Its catalytic activity in m-xylene isomerization at various temperatures different space velocities studied. The influence adding Pt promoter on its also examined. Besides compared with those medium pore SAPO-11 large SAPO-5. showed less than SAPO- 11 higher conversion levels. more presence H 2 carrier gas.
