| Resumen | Transcripción del resúmen publicado por el autor: A series of CuZnAl oxide-composite catalysts have been prepared via decomposition of CuZnAl hydrotalcite-like compounds (HTLcs: Cu 37%, Zn 15%, Al 48% mol) at various temperatures and examined for use with aerobic oxidative desulfurization (AODS) of gasoline-range organosulfur compounds in iso-octane. It shows that catalytically relevant properties of HTLcs-derived CuZnAl catalysts and their performance for AODS reaction can be significantly controlled by HTLcs decomposition temperatures. At 600 °C, CuZnAl HTLcs can be decomposed completely to form highly dispersed CuO with large specific surface area while forming a small amount of CuAl2O4 spinel phase, and meanwhile, improved CuO-ZnO interaction and promoted catalyst reducibility/reoxidizability can be obtained. By taking the above beneficial properties, this HTLcs-derived CuZnAl catalyst is quite active and selective for aerobically oxidizing organosulfur compounds to SO2 at 300 °C and atmospheric pressure. Thiophene is not so reactive as mercaptan, organic sulfide, benzothiophene, and dibenzothiophene. Adsorptive oxidation of thiophene previously observed on Pt/CeO2 catalyst is likewise detectable on this HTLcs-derived CuZnAl catalyst by means of in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), but it hardly happens to paraffinic, olefinic, and aromatic hydrocarbon molecules. |
