Abstract. Evidence for the mechanistic link between low pressure studies and the high pressure, aqueous phase, catalytic partial oxidation reactions of ethanol on gold is provided. The oxidation of ethanol on gold (111) leads to the formation of ethyl acetate and acetic acid, as was also reported for this reaction over supported gold catalysts in aqueous phase. This reaction follows a patte…
Abstract. In situ microprobe Raman and XRD techniques were used to follow the oxidation state of Rh/Al2O3 and Ru/Al2O3 catalysts during the catalytic ignition process of the partial oxidation of methane (POM) to synthesis gas. It was found that the catalyst was in the fully oxidized state before ignition of the POM reaction, and abruptly changed its oxidation state at the temperature at whi…
Methane reforming and partial oxidation was studied to evaluate the catalytic effects of coal chars and coal ashes on methane (CH4) conversion, sum selectivity (the sum of H2 and CO), and ratio selectivity (the ratio of H2/CO) in an atmospheric fluidized bed. The kinetics study presented the possibility of CH4 reforming and partial oxidation with a favorable H2/CO ratio, greater than 5. The …
Th e generic placement of Prenanthes faberi Hemsl. (Compositae – Cichorieae) has long been a controversial matter. Recent molecular phylogenetic analyses indicate its inclusion in the genus Faberia Hemsl. Th e present cytological investigation shows that this species has a chromosome number of 2n 34 and a fairly symmetric karyotype consisting of 26 median centromeric (m) and 8 submedian cen…
