The thermal and hydrothermal stability of MSU-2 increased with the increasing silica to alumina ratio,the MSU-2 has a matchable thermal stability with NaY zeolite,and a matchable hydrothermal stability with HZSM-5 (n(SiO 2)/n(Al 2O 3)=38) zeolite.

• 实验结果表明 ,中孔分子筛MSU -2热稳定性与NaY分子筛相当 ,水热稳定性与HZSM -5 (n(SiO2 ) /n(Al2 O3 )为 38)相当 ,随着n(SiO2 ) /n(Al2 O3 )的增大 ,MSU -2的热和水热稳定性增强 ;
