Abstract

The transport properties and the hydroconversion of n-heptane and 2-methyl-hexane over Pt loaded HZSM-5 and HBETA were investigated by in situ FTIR-spectroscopy combined with the evaluation of the kinetic data. Propane and i-butane were the main products observed on the catalyst surface as the temperature increased, while the number of interacting Brønsted acid sites was decreasing. The diffusivities of n-heptane and 2-methyl-hexane were in the same range for HBETA, but a significant diffusion restriction for the monobranched isomer was observed on HZSM-5, which was reflected in a lower reaction rate.
