Abstract

The PtKL catalyst modified by Tm2O3 has been characterized by the n-hexane, methylcyclopentane (MCP) and cyclohexane conversion reaction. The results show that the activity for the aromatization on Pt-Tm/KL zeolite catalysts containing thulium ranging from 0.05 to 0.2 wt.-% is higher than that on the PtKL catalyst, and the stability of the modified catalysts is remarkably improved. The influence of thulium on the surface property of the PtKL catalyst has also been studied with absorbed pyridine IR spectra and adsorption of methanol.
