| Abstract: | Pyridine, CO and SO 2 were used as probes to characterize the mixed oxides Al 2O 3/SiO 2 by TPD technique. XRD study showed mullite was the major composition of the mixed oxides. The tail gases were analyzed by gas chromatography. The results showed that the nanocrystal mixed oxides exhibited a good adsorbability for pyridine, CO and SO 2. During desorption of pyridine and CO, CO 2 was detected in desorbed mixtures and in the case of SO 2 solid sulphur was found. |
