Active sites evolution and regeneration of CrOx-ZrO2-SiO2 catalysts with low chromium content in non-oxidative propane dehydrogenationтезисы докладаТезисы
Аннотация:A series of CrOx-ZrO2-SiO2 (CrZrSi) catalysts with high specific surface area using the one-pot template-assisted evaporation-induced self-assembly process was synthesized. The chromium content was varied from 4 to 9 wt.% assuming Cr2O3 stoichiometry. The catalysts were investigated by XRD, SEM-EDX, Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and temperature-programmed reduction (TPR-H2). The catalysts were tested in non-oxidative propane dehydrogenation at 500–600°C using flow-type fixed-bed reactor.
