Abstract

The hydrogenolysis of tetrahydrofuran (THF) on TiO2, SiO2 and Al2O3 supported Pt catalysts has been investigated in the gas phase at 423–623 K in a pulse reactor. The main reactions are hydrodeoxygenation to butane and decarbonylation to propane. The supports had a marked effect on the selectivity of conversion. On the Pt−TiO2 catalyst mainly butane was formed while on the other two catalysts propane formation was dominant. Based on the results of earlier studies on oxacycloalkanes as well as on data in the literature and the experimental results presented here, a new reaction scheme is outlined for the interpretation of the chemical processes discussed.
