| Outline of Final Research Achievements |
Selective synthesis processes of propylene from bio ethanol was studied. Under our reaction condition, In2O3 catalysts showed less activity for the process, but new mixture catalyst with ratio of Co/CeO2 to Pt/Al2O3 is 2 showed high selectivity for propylene synthesis via acetone as intermediate.
Pt contained in the catalyst rather acts as poison for the propylene synthesis. Co/CeO2 catalysts prepared by using organic acid method were improved Co dispersion, and promoted the propylene yield. Co/CeO2 modified by zinc oxide and lanthanum oxide promotes the acetone produced from acetaldehyde, and Cu added in the catalysts also enhanced acetone selectivity by electronic interactions Cu.
