Pressure swing adsorption (PSA) is one practical process for CO2 separation from the exhaust gases in various industries, such as blast furnace gas in steel works. For optimum design of the PSA process, precise estimation of the adsorption equilibriu

The role of methoxide species in selective formation of iso butene from CO and H 2 over ZrO 2 was investigated by means of 13 C tracer method. Analysis of 13 C 13 C coupling in the formed iso butene showed that 12 CO hydrogenation over ZrO 2 pretr

The adsorbed species on ZrO2 and CeO2 during CO hydrogenation forming branched carbon chains, especially isobutene, (over ZrO2), have been investigated by chemical trapping, in situ IR, and solid-state NMR methods. These indicated that methoxide and

The CO hydrogenation mechanism of selective isobutene formation over ZrO2 and CeO2 catalysts was investigated. The chemical trapping and 13C tracer studies showed that branched chain is formed by the carbonylation of C1 species produced from C-O bond

The CO–H2 reaction over ZrO2 was studied in detail. Methanol and isobutene were selectively formed at 473–523 and 623–673 K, respectively. The activation energies for C2, C3, and linear C4 hydrocarbon formation are 79, 84, and 96 kJ mol−1 (52

The Raman spectra of 1,3-dimethyl-2-imidazolidinone were found to change due to a hydrogen bonding to its nitrogen atoms, especially at low temperatures. The change in the spectra included the unusual change for CH2 bending vibrations, suggesting tha
