Abstract Details

2005, MS, University of Cincinnati, Engineering : Chemical Engineering.
Intracrystalline mass transfer is highly limited in the zeolite framework due to its highly microporous structure. The generation of mesoporosity in 1-dimensional zeolite ZSM-12 is investigated in this work. Carbon black was applied as the second template during the synthesis. After the carbon particles were burned off, intracrystalline mesopore networks were formed. The mesoporous ZSM-12s possessed higher activity in terms of cracking of relatively bulky hydrocarbon compounds under relatively high space velocity. Desilication of ZSM-12 was carried out by alkaline treatment. Mesopores around 20-40 nm were formed in the ZSM-12 framework. The volume of mesopores created could be adjusted by varying NaOH concentration, treatment temperature and time. For the ZSM-12 with higher Al content, Si was relatively difficult to extract. Bulky hydrocarbon compounds were proved to have higher diffusivities in the mesoporous ZSM-12 framework.
