✦ Synopsis


The effect of the hydride-forming intermetallic compound Zr2Fe on the aromatization of ethane over Pt,Ga/HZSM-5 catalyst has been studied under different reaction conditions (temperature, GHSV, ethane dilution with Ar). In the presence of intermetallic hydrogen acceptor aromatics yield from ethane at 500°C was 6-fold higher and reached 61 wt.-% as a result of releasing hydrogen elimination, selectivity to aromatics being 78%. The fused-ring aromatics formation appeared to be more sensitive to hydrogen removal than BTX formation. The yield of BTX may be improved by ethane dilution with inert gas.

In this work, the effect of the metal nature on the reaction mechanism of the partial oxidation of ethanol on Pt/CeO 2 and Rh/CeO 2 catalysts was studied by using diffuse reflectance infrared spectroscopy (DRIFTS) analyses. The results showed that the nature of the metal affected the reaction mechan
