We have prepared a series of well-characterized acid catalysts, including Zr–P, SiO 2 –Al 2 O 3 , WO X /ZrO 2 , γ-Al 2 O 3 , and HY zeolite and tested them for aqueous-phase dehydration of xylose. We have characterized the concentration of both Brønsted and Lewis acid sites in these catalysts with TPD and FT-IR spectroscopy using gas-phase NH...
Recent studies suggest that microwave energy can be employed in catalysis and that the results differ from “conventional” heating. The influence of microwave energy on automotive exhaust catalysis in the presence and absence of a catalyst poison (SO2) was studied. The conclusion is that microwave energy can induce carbon monoxide (CO) lightoff (the temperature where 50% of final conversion is achieved)...
