Abstract
Abstract: The Pt KL 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 Pt KL catalyst, and the stability of the modified catalysts is remarkably improved. The influence of thulium on the surface property of the Pt KL catalyst has also been studied with absorbed pyridine IR spectra and adsorption of methanol.
