- W2016021213 abstract "The isomerization of n-butenes was studied over zinc oxide in a glass recirculation system. Experiments were made with each of the pure isomers at temperatures between 0 and 90 °C. At low temperatures and conversions the reactions were all zero order in olefin. Below 50 °C the Arrhenius plots were linear so that the reaction coordinates of the system could be mapped. At 90 °C, the reaction was no longer zero order. These results indicated that the reaction occurred in the nonlinear part of the adsorption isotherm. Tracer experiments using cis-2-butene-2,3d2 showed that cis-2-butene can be converted directly into the trans- isomer (without going through 1-butene as an intermediate). At higher temperatures both the kinetic data and the tracer results were complicated by secondary processes. The tracer studies of these reactions were also carried out over a γ-alumina catalyst. Experiments were made using cis-2-butene-2,3d2 and cis-2-butene-d8 as well as binary mixtures of these compounds. In contrast with ZnO, intermolecular exchange was important over alumina, particularly in the 1-butene product. CO2, which is a good poison for olefin-D2 exchange, was not nearly as effective for intermolecular exchange. Moreover, the alumina OH groups contributed to the intermolecular exchange under the reaction conditions. ZnO behaved as an “ideal system” in which the kinetic and tracer data were entirely consistent with the previous ir studies (Dent A. L., and Kokes, R. J., J. Phys. Chem. 75, 487, 1971; Chang, C. C., Conner, W. C., Jr., and Kokes, R. J., J. Phys. Chem. 77, 1957, 1973) of the intermediate species. Although on alumina the picture was obscured by simultaneous exchange processes, comparison of the present results with other published data led to the conclusion that, the mechanisms for n-butene isomerization over ZnO and alumina are the same or very similar at temperatures below 100 °C." @default.
