Heterogenized homogeneous catalytic systems for the oxidation of carbon monoxide and propane

Heterogenized catalysts were prepared by the immobilization of the homogeneous catalytic systems containing the rhodium complexes, copper compounds, and perfluoroorganic acids onto porous carriers. The activity of the catalysts was studied in the processes of CO oxidation and co-oxidation of CO and propane. The state of the catalyst components was determined and the possibility of their interaction was evaluated by X-ray spectroscopy (XANES and EXAFS) and electrospray mass spectrometry (ESI-MS). The oxidation of CO on the RhCl3-CuCl2-C3F7COOH/γ-Al2O3 catalyst in a flow reactor at 70–80 °C and atmospheric pressure occurs in an oscillating mode. The co-oxidation of propane and CO at 80–95 °C and a pressure of 1.0–1.5 MPa is basically possible but occurs with a low yield of propane oxygenates.
