Abstract

The hydrodeoxygenation of 2-methoxyphenol (guaiacol) has been studied over a MoS 2 catalyst supported on two activated carbons with marked differences in porosity and oxygen surface functionality. The catalysts were prepared by rotary evaporator impregnation and characterized by BET surface area and XPS, while the supports were characterized by TPD, PZC, FTIR, BET and XPS techniques. The reaction was studied in a batch reactor at 300°C and 5 MPa. Activity differences on the carbon supports are correlated with the dispersion of MoS 2. Greater abundance of surface oxygen (mainly carboxylic, quinonic and lactonic groups) on the support resulted in lower catalyst dispersion and lower HDO activity. The dispersion, textural properties and surface chemistry did not affect the nature of the MoS 2 active sites.
