摘要：

SBA-15 acid catalysts were prepared using two different post-synthesis methods, alumination followed by ion-exchange (H-Al/SBA-15) and styrene polymerization followed by sulfonation (H-SP/SBA-15). For the H-Al/SBA-15,1-hexene conversion and C-10+ selectivity tended to increase with increasing pore size, although there were no significant differences higher than 7 nm. For the H-SP/SBA-15, the conversion and C-10+ selectivity increased with increasing amounts of polymers but there was also an optimum range (20-25 wt.%). The overall results demonstrate that controlling the acid properties of the mesoporous SBA-15 is much more critical to 1-hexene oligomerization than improving diffusion limitation by modifying textural properties.
