Decane Hydroisomerization Test Probing Catalytic Activity and Selectivity of Aluminum and Boron Substituted Extra-Large Pore UTL Zeolite

摘要

Extra-large pore germanosilicate zeolite with UTL structure was tested in the n-decane hydroisomerization/hydrocracking reaction. The product selectivity demonstrated UTL to be the most open zeolite material ever characterized with the decane test. Al- and B-containing samples were synthesized with high degree of crystallinity. The incorporation of part of the heteroelements was confirmed with 27Al and 11B NMR spectroscopy. The catalytic activity and the structural stability of these samples was significantly lower compared to germanosilicate UTL and followed the sequence: UTL > Al-UTL > B-UTL.
