摘要: Abstract The kinetics of carbon monoxide and propylene oxidation on Cu 0.8 CO 2.2 O 4 , CuCr 2 ZnCr monophase spinels were studied in a differential recycle reactor. activities agree fairly well with those observed pulse flame reactor the utilization isooctane combustion products as feed passed over catalysts, i.e., under similar conditions to real spark engine exhausts. high content methane other saturated hydrocarbons this influenced decrease rate total comparison pure propylene. For ageing catalyst, doped ethanethiol was used. amount sulphur bonded sample surface from SO 2− ions, determined by X-ray photoelectron spectroscopy, is not proportional reduction spinel activity. This fact attributed fine structure spinels.
