Partial oxidation of propane in compressed carbon dioxide using CoO /SiO2 catalysts

Heterogeneously catalysed partial oxidation of cyclohexane in supercritical carbon dioxide

“…The conversion of methane and ethane in scCO 2 yields corresponding alcohols, aldehydes and acids similar to gas phase experiments [18]. In our group, we have intensively investigated the partial oxidation of propane over metal oxide catalysts in scCO 2 [19][20][21]. The product distribution was unlike the results from gas phase runs (formation of, e.g.…”

“…Otherwise, we observed a significant influence of scCO 2 density on conversion and selectivity for oxygenated products. The most likely explanation is the improved desorption of oxygenated intermediates from catalyst surface in near-critical region before total oxidation occurs [19].…”

Methanol oxidation over model cobalt catalysts: Influence of the cobalt oxidation state on the reactivity

“…Perhaps the major application of cobalt-based catalysts is in the Fischer-Tropsch synthesis, since cobalt has been shown to efficiently convert syn gas (CO+H 2 ) to methane or liquid fuels [8,9,10,11]. Other applications of cobalt catalysts include partial oxidation reactions [12] and decomposition of methane to form hydrogen and carbon nanotubes or filamentous carbon [13,14]. Recently cobalt has been proposed as a very promising catalyst to replace noble metals for H 2 production by steam reforming of ethanol [15,16].…”

Catalytic Performance of Fe(II)-Scorpionate Complexes towards Cyclohexane Oxidation in Organic, Ionic Liquid and/or Supercritical CO2 Media: A Comparative Study

“…The influence of scCO 2 density on the selectivity for oxygenated products from the oxidation of cyclohexane has been reported previously [37]. A higher density leads to a higher selectivity, since the formed oxygenates are believed to be removed more easily from the catalyst surface without being totally oxidized due to the higher solvent power of the denser CO 2 in the supercritical phase [39].…”
