HZSM-5 and H-ferrierite acidity modification by silylation and their activities in n-butene isomerisation
(Walter de Gruyter, 2010)
H-ZSM5 and H-Ferrierite acidities were modified by chemical liquid deposition using tetraethylorthosilicate (TEOS), silicontetratchloride (SiCl4) and triaminopropyltriethoxysilane (3-APTES). All depositions were carried ...
Effect of different acidity modifications on the activity and selectivity on H-ZSM5 zeolites in n-butene isomerization
H-ZSM-5 was modified by silylation [tetraethylorthosilicate (TEOS) and triaminopropyltriethoxysilane], alkali (NaOH), acid (HCl) and ammoniumhexafluorosilicate (AHFS) treatments. The parent and modified zeolite forms were ...
