Characterization of zeolite SSZ-35 by catalytic hydrocarbon conversions
The synthesis of SSZ-35, a high-silica zeolite with unusual pore architecture (onedimensional channels circumscribed by 10-membered and 18-membered rings in an alternating manner), was achieved with nSi/nAl ratios from 11 to >500. The catalytic properties and the pore architecture of its bifunctional form (0.27Pd/HSSZ-35) were characterized using the isomerization and hydrocracking of n-decane. As expected, the catalytic activity increases with increasing Al-content of the zeolite. Moreover, the product distribution is influenced by shape selectivity effects resulting from the presence of 10-membered ring sections in the unidimensional pores. In contrast to zeolite Y, the pores of zeolite SSZ-35 restrict the formation of bulky ethyloctane and propylheptane isomers.
