Abstract

Hybrid catalysts with the external configuration for the cocatalyst showed enhanced product diffusion rates in the n-octane hydrocracking, only if the reaction was carried out at relatively high temperatures. In the n-heptane isomerization, direct incorporation of the Al species into the HY zeolite micropores produced sorption sites which positively affected the selectivity to liquid isomers. Such as internal hybrid configuration resulted in a more important increase in the liquid isomer selectivity than that given by the external hybrid configuration, both systems being designed for better product outward-diffusion.
