| Popis: | CO hydrogenation in the presence of dimethyl ether (DME) was carried out on some selective catalysts for the formation of isobutene. ZrO2, ZrO2–CeO2, ZrO2–CeO2–CoO showed a high enhancement effect on hydrocarbon formation, CeO2 almost no effect, and ZrO2–CeO2–Fe2O3 formed methane selectively. CO hydrogenation on DME-preadsorbed CeO2 resulted in an increase in methane production and the retardation of the other hydrocarbons. The preadsorption of dimethoxymethane was most effective for the formation of ethene. The reaction path of methoxy species to methyl and methylene was discussed. |
